I wanted to comment you that, in my Gretl 1.6.1, the
correlation matrix, cross tabulation, main components,
Mahalanobis distance and cross correlogram are always inactive,
independently of the type of data set I have (time series, cross
section or panel data), is there any problem with it?? Maybe is
necessary install any specific program to complete Gretl (like
TRAMO or ARIMA X12)
You just have to select more than one variable in the main window,
then these items become active.
