[Gretl-users] Marginal effects calculation - RE probit & FE logit

Hi, I am running FE logit (function package of Lucchetti) and RE probit but there is no option for calculating slopes and different kinds of marginal effects. I downloaded the function packages a_eff of Komashko e lp-mfx of Cottrell but it seems there is no possibility to run them on FE logit and RE probit. I need marginal effects for evaluating my regression, how can I calculate them? Thanks in advance, Martina
