Parameters setting in functions optimization
...correct settings for
function like "optimx" and "nlminb".
I'd like to minimize my parameters and the loglikelihood result of the
function.
My parameters are a mean distance of dispersion and a proportion of
individuals not assigned, coming from very far away.
The function LikeGi reads external tables and it's working as I want
(I've got a similar model on Mathematica).
My "final" function is LogLiketot :
LogLiketot<- function(dist,ms)
{
res <- NULL
for(i in 1:nrow(pop5)){
for(l in 1:nrow(freqvar)){
res <- c(res, pop5[i,l]*log(LikeGi(l,i,di...
