## st: Help with Clogit/Fixed Effects Logit

To whom it may concern:

I have a paper where I am examining the impact of democracy on crisis behavior. I need to estimate a fixed effects or conditional logit model but I am not sure how.

The data is set up dyadically, meaning each observation has data on the crisis and data for state A in the crisis and state B in the crisis

Here is the functional form of the logistic regression I have run

logit DV democstateA democstateB control1 control2 control3 control4

I need to estimate a fixed effects model to control for the impact of specific countries. I know that I need to use conditional logit to control for unmeasured heterogeneity.

But I am not sure how to do it. Specifically, in the clogit setup, it should look like:

clogit DV democstateA democstateB control1 control2 control3 control4, group(????).

What I am unclear about is what goes in the parentheses. If anyone could assist, I would very much appreciate it. I apologize for asking such a basic question.
