Installation and Operation of ODBC Drivers
If you want to retrieve data from databases in a network environment (local area or wide area network), contact your SPSS system administrator for information about how to configure your desktop computer with ODBC data sources If you are a system administrator, please
read Getting Started with SPSS Data Access Technology in the Installation Documents
Trang 2directory on the CD-ROM.
If there is no system administrator at your site you can install and configure ODBC data sources yourself
Installable versions of ODBC drivers from SPSS Connect ODBC and Microsoft are available
on the CD-ROM We recommend that you use the SPSS Connect ODBC drivers unless you need a driver for Microsoft Access
Instructions for installing the SPSS Connect ODBC drivers and the Microsoft Access Driver
are in SPSS Data Access Pack Installation Instructions, included in the Installation Documents directory on the CD-ROM.
Refer to the Known Issues and Problems in SPSS 11.5 for Windows section below for specific
ODBC driver issues
New Features in SPSS 11.5 for Windows
• New data definition tools Two new features make defining data faster and easier:
• The Copy Data Properties wizard provides the ability to use an external SPSS data file
as a template for defining file and variable properties in the working data file You can also use variables in the working data file as templates for other variables in the working data file This wizard uses the improved APPLY DICTIONARY command which offers many new features for copying variable and dictionary properties
• Define Variable Properties scans your data and lists all unique data values for any selected variables, identifies unlabeled values, and provides an auto-label feature This
is particularly useful for categorical variables that use numeric codes to represent categories (for example, 0 = Male, 1 = Female)
• TwoStep Cluster Analysis This new clustering procedure provides the following features not available in the other SPSS clustering procedures:
• Automatic selection of the best number of clusters, plus measures for choosing
between cluster models
• Create cluster models simultaneously based on categorical and continuous variables
• Ability to save the cluster model to an external XML file, then read that file and update the cluster model using newer data
• Ability to analyze large data files with a single clustering procedure
• New Custom Tables option If you have used the Tables option in the past, you will quickly discover that just about everything in it is new for this release, including:
• A simple drag-and-drop table builder interface that allows you to preview your table
as you select variables and options
Trang 3• A single, unified table builder interface instead of multiple menu choices and dialog boxes for different types of tables
• Subtotals for subsets of categories of a categorical variable
• Custom control over category display order and ability to selectively show or hide categories
Note: Custom Tables is not included in the SPSS Base system It is only available if you have purchased the Tables add-on option
• Expanded support for SAS format data files You can now save data files in SAS Version 6, SAS Version 7, and SAS Transport file format
• Expanded output export capabilities You can now export entire Viewer
documents or selected output objects in Word/RTF format and Excel format (charts are not included in Excel format)
• Multiple output languages You can now produce pivot table output in different languages and switch languages during the same session
Known Issues and Problems in SPSS 11.5 for Windows
New multiple response sets – Although the Original Tables module allows one to create
multiple response sets which are used in the TABLES procedure, these sets can only be persisted in a system file from an SPSS for Windows dialog The new Custom Tables module has a new dialog which makes use of a new syntax command (MRSETS) for creating multiple response sets Although the new mechanism offers some improved functionality, there may be problems using a new multiple response set with the old Original Tables module
Using data files saved in SAS formats in SAS JMP and the SAS Viewer – Data files saved
in various SAS formats from SPSS should work in SAS There are known problems using SAS files saved in SPSS with the SAS Viewer and SAS JMP 5 – these applications have a different mechanism for reading files which isn’t the same or as stable as the one used in SAS
Filename limitations for data files saved in SAS formats - The following excerpt is from
the SAS JMP 5 README: “Double-byte characters should not be used in filenames when writing SAS files [from within JMP] This is a limitation of the SAS local data provider that
is to be corrected in version 9 of SAS” This holds true for SAS files saved in SPSS
Using data sets with a large number of cases in the Data Editor - When data are read in to
SPSS, memory is allocated in the Data Editor to accommodate all of the cases If a very large data file (millions of cases) is opened (even when connected to an SPSS Server) it is possible that the computer running SPSS for Windows will run out of virtual memory
The number of cases that can be held in memory by the Data Editor can be limited by a special setting This threshold can be set by using the virtualr.exe utility, which is located in
Trang 4the SPSS installation directory The default is to allocate memory for up to 100,000 cases as needed If a Data Editor-specific operation is used to pass the threshold, such as scrolling to the end of a large file, memory for all of the cases will be allocated
The threshold setting does not affect the ability to carry out any operations in SPSS for Windows, but it may affect performance with large datasets You should not change the default unless you have memory exhaustion problems In that case, set
a smaller value using VirtualR
Switch Output Language - The Switch Output Language feature allows you to get output in
various languages other than English The translations included with this English installation are not final Some items may still be in English, and some translations may change Updated files will be available for download from the SPSS website at http://www.spss.com/tech/downloads/
Text Import Wizard and characters - SPSS cannot process string values longer than 255
characters Before you import the data, edit it to reduce the length of the strings If you encounter
a problem importing a value that contains a foreign character, edit the file and remove the
character to fix the problem
Caching data - The Database Wizard and the Text Wizard provide an optional setting that
automatically caches the data that they import By default caching is on and the wizards create a copy of the entire dataset If you turn caching off, SPSS does not have access to the entire data file the original data source is re-read as needed and the total number cases is unknown
When the total number of cases is unknown, Go to Case, Copy, and Paste do not work as
expected in the Data Editor You can correct the problem by turning caching on
Performance with wide files - If your data file has many columns, you can improve the
performance of the graphical user interface by setting your General Options to avoid displaying
variable labels in alphabetic order Select Options from the Edit menu, and go to the General tab
to set options for Variable Lists The other combination of options perform well.
Specifying substitution fonts when converting TrueType to PostScript in EPS exports -
When exporting charts or maps from the SPSS Viewer to Encapsulated PostScript (EPS), one may choose an option to convert TrueType fonts to PostScript fonts Although the default behavior of this option is match up a TrueType font with a PostScript font family for conversion, one can explicitly specify a substitution PostScript font in the IEx_Font.ini configuration file located in the SPSS installation directory (directions and samples included) This feature may prove useful for users of multi-byte text who require conversion to a specific PostScript font
C:\…\LOCALS~1\Temp\spss####xxx.tmp contains an invalid path - There is a defect in SPSS
which manifests itself when one first starts SPSS after a fresh install and runs a procedure after making changes to the Options settings under the Edit menu This defect will not reappear after one closes down SPSS and restarts
Installing Multiple Copies of Adobe Acrobat - It is highly recommended that you only install
one version of Adobe Acrobat on a computer Some browsers might have problems loading multiple plug-ins for multiple versions of Acrobat If you wish to upgrade to the version of
Trang 5Acrobat which is located on the SPSS CD-ROM, please uninstall all other versions first.
Oracle and SequeLink Server - If you are using the SequeLink Server at your site, it might not
work correctly with Oracle 8 Use Connect ODBC instead Connect ODBC is included in the SPSS Data Access Pack
Japanese characters in Data Direct driver setup - Japanese characters cannot be specified in
the Data Source Name or Description of the version of Data Direct database drivers which are shipped with SPSS 11.5 Data Direct acknowledges that this is a problem, and plans to release a fix
Enhanced Metafiles (EMF) cropped in Internet Explorer - SPSS Viewer objects exported as
EMFs are cropped when viewed using Internet Explorer Netscape cannot read the EMF format
It is recommended that more popular image formats be used for use with browsers
SPSS doesn’t work with Altiris Vision User Module 3.1 - There is a memory conflict with
Microsoft DirectDraw and SPSS when Altiris Vision is installed using the “Run before logon” option In order to resolve this problem you must not install Altiris Vision with this option - use
"Add to startup menu" or "Run manually" instead You must uninstall and re-install Altiris Vision if you already have an installation using “Run before logon” and are experiencing
problems
Linear Mixed Models -
§ In the Random dialog box if the Include Intercept checkbox is checked but no
factors or covariates are specified as random effects, the Next button will not become available Therefore, in order to generate a RANDOM subcommand with
no effect(s) other than an intercept, that subcommand must be the last one specified in the Random dialog box If there are multiple subcommands specified, the last of which contains only the intercept, that specification will not be generated unless Continue is clicked while remaining at that last specification, unless that specification also includes a subject combination
SPSS Maps - The SPSS Map Option contains the following known problems or
requirements:
§ Running a network installation of SPSS - The Map Option will not run from a
network installation If you need to run the map option, install SPSS on your desktop computer
§ Limited number of ranges in Range of Values map - If you save an output file
that contains a Range of Values map that has more than five ranges defined, you will not be able to reopen that file Therefore the limit on the number of ranges in
Trang 6the Create Range of Values Map dialog has been set to five You can create a Range of Values map with more ranges using syntax or by editing the map, and you can copy that map as a metafile into another application such as a word processor; but if you save the SPSS output file containing such a map, you will be unable to open the file at all The problem is in third-party software SPSS Inc has not yet been able to obtain a fix from the software vendor, but will distribute a patch as soon as the fix becomes available
§ Range of Values map causes application error with Natural Break and no
data - If your data specification results in no data records for mapping, the Natural
Break formula for determining ranges fails with an application error This most commonly happens if your choice of a geoset or layer within a geoset does not correspond to your data A mismatch table should be produced to indicate this problem, but the application error prevents it from being shown
§ Copy Objects unavailable with maps - Maps are copied to other software as
metafiles Copy Objects will not work correctly A side effect of this is that you must copy and paste maps one at a time
§ Bar chart and pie chart map theme size not restored - Changes you make to
the size of bar charts and pie charts in editing maps are not retained when the map
is saved and restored
§ Variable to refine geographic match can cause SPSS to hang - If you use both
a geographic variable and a variable to refine the match, the resulting data table can exceed the capabilities of Maps and cause SPSS to hang Most significantly, with United States data, if you use County and State as your geographic and refining variables and have data for more than a few states, you will experience this problem If you are using the various county-level data files distributed with SPSS Maps, you can avoid this problem by specifying the 5-digit FIPS codes as your geographic variable and no refining variable FIPS codes identify counties uniquely For data containing state and county variables but not FIPS codes, a solution to add FIPS codes to the data will be available on the SPSS web site
§ Maps require updated system resources - If it has been a while since you added
Microsoft products to your system, you may have outdated system resource files Installing Internet Explorer 4 or 5 (required for the SPSS Statistics Coach) will update those files
§ Error messages may appear during install under NT - If you have a version of
NT 4.0 that has not been updated recently, you may see messages during installation about failure of geoset installation The SPSS installation replaces the system resource file required for successful installation, which will take place after you reboot your machine at the end of the SPSS installation You can safely dismiss and ignore the warnings
§ Maps does not use the FILTER or WEIGHT commands - This could lead to
