Hi,

I have 2 datasets (1 & 2) that have 4 variables in common (A, B. C, D). How do I find the frequency (or count) of the common values found in both datasets?

Variable A is the merge by variable.

For example:
Dataset1:
Variable B has 50 records containing one of these values (10, 15, 25, 45...)

Dataset2:
Variable B has 150 records containing one of these values (10, 15, 25, 45, 65 80...)

How can I produce an output like this?

Frequency of common values between dataset1 and dataset2:

VariableB      
Value    Dataset1 Freq       Dataset2 Freq   Common Freq     % of Total      Total (combined)
    10               75                                80                        50                25.0%                 200
    15               25                                40                        25                12.5%                 200
    25               50                                80                        10                   5.0%                200

And so on for Variables C and D...
Thanks in advance
