Dear all,

I have the following data coming from a lab experiment from multiple sessions. Under each session I have 6 treatments and under each treatment subjects play for 30 periods. I have 10 subjects for each session. From the data I am trying to create a dummy variable. The dummy should take a value 0 if n2=n3, and take a value 1 if n2!=n3 for all the subsequent periods. For example for each treatment, if the inequality occurs at period 18, the dummy should take a value 1 from period 18 onward. If the inequality occurs at multiple periods, say for example, at periods 5, 13 and 19, the dummy should take a value 1 starting from period 5. Below is a snippet of the data. I would appreciate any help with creating the dummy variable.

Thanks,
Anwesha
