Interpreting results from mfx

[Z G Dapel]

Dear All,
Please help with idea on interpreting results from marginal fixed effects. I run a simple regression. Dependent variable is 't' ( natural log of years) and independent variable is 'g' (growth rate in percentage). After 'margins, at(g=80), command, I got the value of 0.4354895. Can someone please tell me the meaning? Thanks

- as per FAQ again, you are kindly requested to provide the list with what you typed (exactly) and what you got from Stata as a result.

Kind regards,

You are probably getting the predicted value of t when g = 80, but you should show the complete commands and output so we can be sure.

If you want an introduction to margins and the very helpful mcp command, see

- as Richard says, you obtained the predicted value of lnt when g=80.

Kind regards,
