I have a dataset in the following form, with the input variables Var 1 to Var 3 and required output variable:

Var1     Var2     Var3      OutputVar

a          1          p              1

a          1          q              2

a          2          r               1

b          1         m              1

b          2         n               1

b          2         o               2

For each Var1, the OutputVar needs to be the cumulative frequency of Var 3 grouped by Var2. I need all the variables in the final output data.

Any suggestions please?

Thanks.
