Re: [R] Optim function in the loop

Thanks for the reply. optim(initpar,Linn,NULL,method="BFGS",hessian=TRUE,control=list(trace=1,REPORT=1,maxit=300)) The optim is to minimize the negative likelihood function which is performed in function "Linn", Every time the code stops right after optim, for example, the output looks like: "
