Hi, Im just doing some Beta-Regressions with the betareg package. My question is now, is there a possibility to calculate the marginal effects with the betareg package or is there another package which can handle marginal effects on regression output for the "beta" class? I try to calculate the marginal effects also by hand but then i have the problems with the standard errors :-( Thx alot Chris -- View this message in context: http://r.789695.n4.nabble.com/Marginal-Effects-for-Beta-Regression-tp3761895p3761895.html Sent from the R help mailing list archive at Nabble.com.
