GENERATE MATRIXName:
The specified statistic should require exactly two response variables to compute. Examples include correlation and covariances, various distance measures, differences of location or scale statistics, and so on. Statistics that require a single response variable or more than two response variables will return an error. A number of supported statistics that require two response variables have the second variable as a groupid variable. Although this command will not generate a syntax error for these cases, the resulting statistics will not be meaningful.
<SUBSET/EXCEPT/FOR qualification> where <stat> is one of Dataplot's supported statistics that requires exactly two response variable; <var1> ... <vark> is a list of previously defined variables; <mat1> is a matrix where the resulting matrix is saved; and where the <SUBSET/EXCEPT/FOR qualification> is optional.
