This article explains how...  Continue reading Coloring Significance in SPSS Statistics Custom Tables Output

Using SPSSINC PROGRAM and generalizing your code vs writing macros in SPSS Statistics

Suppose you want to generate all two-way crosstabs for a set of variables in your dataset but without creating any of the redundant transposed tables (V2 BY V1 and V1 by V2). You could, of course, write a lot of CROSSTABS commands, but that would be very tedious and error prone. You could...  Continue reading Using SPSSINC PROGRAM and generalizing your code vs writing macros in SPSS Statistics
