Hi Folks, I am trying to work with spatial logit model and I stopped my research in a Paper of Pinkse that make estimation of spatial models by GMM. I search in R communite and I find that GMerrorsar function in spdep package is used to it, but I have tryied so many times to make my model by this

[R] Problems if optimization

What's up fellows... I am a begginer in R and i am trying to find the parameters of one likelihood function, but when i otimize it, always appers a error or advertisement and the solve does not occur. The problem seems like that: "lMix<-function(pars,y){ beta1<-pars[1] beta2<-pars[2] beta3<-pars
