    Hi guys I am running a glmm model for my data, the Type III tests of fixed effects is showing that there is a significant effect of treatment but when i run the multiple comparisons, non of the treatment levels are significant. What causes this confusion? Is my model not right maybe? Regards...

    Compare regression coefficients across groups in panel data

    Dear TalkStats users, I am wondering how to test for differences in regression coefficients across groups in panel data (after a fixed-effects regression). Particularly, I can't think of a solution of how to construct interaction terms if the groups you are interested in are not the same...

    Fixed effects versus standard errors

    I have experimental data from a correspondence test in the rental housing market. On which ground should I choose between: 1) F.E. for the region where the apt is and cluster s.e. on the day I sent the message 2) cluster s.e. on region and F.E. on day when the message was sent (or...

    Logistic Regression - Equation

    Hi! I run a logistic regression, and i know that it can be written as Pr(y=1)=F(a+b_1*x+b_2*z). With y being the dependent variable, a the intercept, b_ the coefficients and x&z the independent variables. Concerning the notation only: Any ideas how I could write this for x and z being...
