Subject | st: Fwd: Error standards for margins effects in multinomial logistic regression |
Date | Wed, 10 Apr 2013 18:19:17 +0200 |
Hello, I am running a multinomial logistic regression and in order to interpret the results I have calculated the average margin effects. All variables are treated as factors and there are also interactions. More precisely, this is the code. #delimit; mlogit grupos experiencia_g2##sexoSS experiencia_g2##edad_SSr experiencia_g2##menor2_r experiencia_g2##tip_conr experiencia_g2##grup_co_r experiencia_g2##act_eco_rf experiencia_g2##trab_ccs_r experiencia_g2##nivel_est1_r if grupos<5, vce(robust); #delimit; margins, dydx(*) at(experiencia_g2=(1 (1) 4)) predict(outcome(1)) vsquish vce(unconditional); margins, dydx(*) at(experiencia_g2=(1 (1) 4)) predict(outcome(2)) vsquish vce(unconditional); margins, dydx(*) at(experiencia_g2=(1 (1) 4)) predict(outcome(3)) vsquish vce(unconditional); margins, dydx(*) at(experiencia_g2=(1 (1) 4)) predict(outcome(4)) vsquish vce(unconditional); In the logistic regression some coefficients appear as not significant, whereas the marginal effects are significant. Why is that possible? In order to analyse the results, which ones sholud I consider?
