What’s new in version 21?
Simulation. Predictive models, such as linear regression, require a set of known inputs to predict an outcome or target value. In many real world applications, however, values of inputs are uncertain. Simulation allows you to account for uncertainty in the inputs to predictive models and evaluate the likelihood of various outcomes in the presence of that uncertainty. See the topic Simulation for more information.
One-click descriptive statistics. Select variables in the Data Editor and get summary descriptive statistics (for example, mean, median, frequency counts). Appropriate statistics are automatically determined based on measurement level. See the topic Obtaining Descriptive Statistics for Selected Variables for more information.
Read Cognos Business Intelligence data. If you have access to an IBM® Cognos® Business Intelligence server, you can read data packages and list reports into IBM® SPSS® Statistics. See the topic Reading Cognos data for more information.
Merge data files without pre-sorting. Merge data files by values of key variables without pre-sorting the files based on key values. You can also merge data files based on string keys of different defined lengths in each file and merge a case data file with multiple table-lookup files with different keys in each table-lookup file. See the topic STAR JOIN for more information.
Compare datasets. Compare the data values and metadata attributes (dictionary information) of two datasets. See the topic Comparing datasets for more information.
Password protect and encrypt data and output files. See the topic Encrypting data files and output documents for more information.
Pivot table editing enhancements. After creating pivot tables, you can now:
• Toggle the display of names, values, and labels. See the topic Controlling display of variable and value labels for more information.
• Sort table rows. See the topic Sorting rows for more information.
• Insert rows and columns. See the topic Inserting rows and columns for more information.
• Change the output language. See the topic Changing the output language for more information.
Export output in Excel 2007 and higher format. See the topic Export output for more information.
Preserve table styles when exporting output to HTML. All pivot table style information (for example, font styles, background colors) and column widths can now be preserved. See the topic HTML options for more information.
Unicode default. SPSS Statistics now runs in Unicode mode by default instead of code page mode. See the topic Unicode mode for more information.
