. gen z = A == 1 & group <.

a will be 1 for every observation that meets the condition and is in a

Dear Statalisters,

I have a question with respect to creating dummy variables.

First, I tabulate data based on a specific condition

tab group if A==1

and the Stata and example output (partial) looks as follows


Group   |      Freq.     Percent        Cum.
-----------------------------------+----------
Group 1 |         34        4.34        4.34
Group 2 |         10        1.28        5.62
Group 3 |         22        2.81        8.43
Group 4 |         35        4.47       13.15
Group 5 |         14        1.79       14.94
-----------------------------------------+---

In my dataset I have more than 30 groups (of which only some meet the
required condition). Therefore my task is to create a dummy variable
which will take the value of 1 if it belongs to any of the groups
which are listed as output from the conditional table and zero
otherwise.

Any help in this direction is much appreciated.

Thanks

Anup
