I ran a logit model, lhs is risk tolerance (=1 if respondent willing to take high risk; =0 otherwise), rhs are demographic factors such as age, generation, year, ... then I used mfx command to show marginal effect. For example, the marginal effect for generation Y was -0.0166503* (5% significant), then my interpretation was "Each respondents belonging to the Y generation decreased the likelihood of reporting risk tolerance by 1.66 per cent." I was told that my interpretation was wrong but I couldn't manage to find where.
