Need advice on appropriate method to use..

[Isla Herrera]

I have survey data of 20+ countries with 9 waves done in 18 years.. however, the respondents are different every year..
Since my dependent variable takes the value of 1 or 0, I am doing probit and logit on stata..
However, I would like to ask for some advice on how to further improve this since (1) it is not really a "panel" data, only a stacked cross-section data and (2) I am suspecting endogeneity problem with my main independent variable..
Hoping for a reply..

I say this all the time, but any analysis you can do is limited by your dataset. Without knowing your question, you're looking at pooled cross sectional data methods. Not much more you can do beyond just that.

Hello, Jared, thank you for your response. What is the "pooled cross sectional data method" I can use? What additional steps should I do when doing a logit and/or probit to make it appropriate for my type of dataset?
