SPSS 16.0更新:SPSS Base

A new, more flexible user interface

The new, Java^TM-based interface makes SPSS even easier to use. You can instantly resize dialog boxes to accommodate long variable names and lists, and quickly drag and drop variables from one pane to another to set up your analysis.

You can easily spell-check variable names and value labels in SPSS 16.0.

This interface also supports Unicode, so that you can work with data in multiple languages from a single application. You can treat text data according to Unicode properties for tasks like sorting and case conversion.

Expanded analytical capabilities

Also, through the SPSS Programmability Extension, an SPSS Integration Plug-In for R is available. This enables users to access the wealth of statistical routines created in R and use them within SPSS as part of SPSS syntax.

Additional programmability enhancements

An SPSS Programmability Integration Plug-in provides the crucial link and configuration instructions that enable an SPSS syntax job to take advantage of a specific external programming language or dynamic link library (DLL). Through the SPSS Programmability Extension, SPSS currently offers the following plug-ins:

SPSS-Python Integration Plug-In
SPSS-.NET Integration Plug-In
SPSS-R Integration Plug-In

New plug-ins are being developed by SPSS Inc. and will be available for download at SPSS Developer Central.

Also available for download at SPSS Developer Central is the new SPSS Programmability Extension SDK. This provides software developers with the information needed to develop an SPSS Programmability Integration Plug-In for a programming language's use with the SPSS Programmability Extension.

Enhanced data management and reporting capabilities

SPSS 16.0 includes many enhancements to data management that users have specifically requested. With SPSS 16.0, you can:

Change the string length or the data type of an existing variable, using syntax
Define missing values and labels for data strings of any length
Choose either to round off or add decimal places to calculated dates when using the Date/Time Wizard
Benefit from new capabilities in the Data Editor, including the ability to:

Find and replace information,
Spell check value and variable labels,
Configure the Variable View, such as the

Ability to sort by variable name, type, or format, etc.
The ability to show/hide dictionary attributes

Find and replace text in syntax, using the Output Viewer, enabling you to detect warnings to identify problems in your output.
Transfer data and SPSS output to and from Excel 2007
Suppress the number of active datasets open on the desktop
Set a permanent default working directory

Reporting enhancements include a new, more powerful visualization engine, which replaces the Interactive Graph Properties (IGRAPH) feature. This makes graph editing faster and easier. (Existing IGRAPH syntax will continue to work.) The enhanced Chart Editor delivers a similar level of functionality as the previous IGRAPH editor.

In addition, SPSS 16.0 introduces Python as the default front-end scripting language. Python supersedes SAX Basic as the scripting language for tasks such as automation of repetitive tasks and customization of output. (Existing SAX Basic scripts will continue to work in SPSS 16.0.)

Greater performance and scalability

In SPSS 16.0, several algorithms are multithreaded, which improves performance on machines containing multiple processors and multi-core processors.

The following algorithms in SPSS Base are multithreaded:

Linear regression
Correlation
Partial correlation
Factor analysis
