  • look for difference in treatment effect between treatment and control group

    Hello,

    I want to look if there is a difference between two groups.

    I run a survey, and half of my participants answer a question hypothetically and the other half of participants will answer the same question, however, I will really implement their decision at the end (incentivized).

    The goal is to look if the answer to this question correlates with the answers to my other questions. First, I need to distinguish between the hypothetical and the incentivized group and look if they correlate similarly with my other questions.

    If there is no significant difference between the two groups, I can put the observations together.

    So I thought about doing it in this way: the incentivized group is like the treatment group and with a dummy I can look for a difference between the treatment and control group (incentivized vs. hypothetical). But I do not manage to do it on Stata

    How can I do that in Stata to compare these two groups?

    Thank you in advance.

    assuming your regressand is categorical (yes/no answer):
    Code:
