Hi!

I know how to perform :
Code:
egen v5 = sum(var4), by(var1)
var1 var4 v5
1 301 4323
1 4022 4323
2 301 623
2 322 623
3 4001 8023
3 4022 8023
4 4001 4323
4 322 4323
5 4001 8023
5 4022 8023
However, would it be possible to divide instead of sum?
For example, I would like to generate this v6 but the divide() function does not exist on STATA

Code:
egen v6 = divide(var4), by(var1)
var1 var4 v6
1 301 0.07483839
1 4022 0.07483839
2 301 0.93478261
2 322 0.93478261
3 4001 0.99477872
3 4022 0.99477872
4 4001 12.4254658
4 322 12.4254658
5 4001 0.99477872
5 4022 0.99477872
Thanks,
Axel
