Hello, I would know the command for the poisson pseudo maximum likelihood in R for my gravity equations. Thank you. Cordially Laurent [[alternative HTML version deleted]]

Hello R-help, According to a research article that covers the topic I'm analyzing, in Stata, a Poisson pseudo-maximum-likelihood (PPML) estimation can be obtained with the command poisson depvar_ij ln(indepvar1_ij) ln(indepvar2_ij) ... ln(indepvarN_ij), robust I looked up Stata help for the command, to understand syntax and such: www.stata.com/help.cgi?poisson Which simply says that the command fits a Poisson regression...
