I apologize for the confusion.

To clarify:

I am doing a meta-analysis.

So basically a group is a set of correlations between two variables. As
I focus on 5 dependent and 20 independent variables, there are 100
combinations. For each combination, I want to calculate the average
correlation (and a whole long list of other statistics).

Now groupd orders the dependent variables into 1 to 5; groupi orders
the independent variables into 1 to 20. Combining both into group would
lead to 100 combinations. Each combination is then used in the next
steps of my analyses.

Does this help?

Thanks again!!
Joep
