Where can I find information on "What's New" in Statistics 21?
The 'What's new in version 21' section is contained in the Statistics 21 'IBM SPSS Statistics Core System User's Guide.pdf' which is part of the Product Documentation download.
I have attached the PDF (IBM SPSS Statistics Core System User's Guide.pdf) to this TechNote.
For a quick reference here is the excerpt of What's new for Statistics 21:
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.
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. For more information, see the topic Obtaining Descriptive Statistics for Selected Variables in Chapter 5 on p. 94.
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. For more information, see the topic Reading Cognos data in Chapter 3 on p. 36.
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.
Compare datasets. Compare the data values and metadata attributes (dictionary information) of two datasets. For more information, see the topic Comparing datasets in Chapter 3 on p. 61. Password protect and encrypt data and output files. For more information, see the topic Encrypting data files and output documents in Chapter 23 on p. 420.
Pivot table editing enhancements. After creating pivot tables, you can now:
· Toggle the display of names, values, and labels. For more information, see the topic Controlling display of variable and value labels in Chapter 11 on p. 233.
· Sort table rows. For more information, see the topic Sorting rows in Chapter 11 on p. 232.
· Insert rows and columns. For more information, see the topic Inserting rows and columns in Chapter 11 on p. 232.
· Change the output language. For more information, see the topic Changing the output language in Chapter 11 on p. 233.
· Export output in Excel 2007 and higher format. For more information, see the topic Export output in Chapter 10 on p. 213.
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. For more information, see the topic HTML options in Chapter 10 on p. 215.
Unicode default. SPSS Statistics now runs in Unicode mode by default instead of code page mode.
