hello! this is one of the two functions i use pen.mle-function(x){ ax-x[32:40] indice-x[1:31] bx-x[41:49] amlebind1-matrix(rep(ax,31),nrow=9,ncol=31) mv-(-(defunciones*log((exp(amlebind1+bx%*%t(indice)))*poblacion)-((exp(amlebind1+bx%*%t(indice)))*poblacion)))

Sorry for posting too much! i found that in Nelder-Mead the result is 1 i run this algorith too many times with several data maybe the problem is that i have to give a bigger number of iterations Lucía -- View this message in context:

I´m triying to give you more information -other function (the problem its the same with both) pen.wls-function(x){ ax-x[32:40] indice-x[1:31] bx-x[41:49] awlsbind1-matrix(rep(ax,31),nrow=9,ncol=31) indice-as.vector(indice-mean(indice)) bx-as.vector(bx/sum(bx)) me-(awlsbind1+bx%*%t(indice))

Ravi please look my last mail. I tried again, and in my last mail i described the results, i reach the convergence but the values are still very diferent. thank you so much! Lucía -- View this message in context: http://r.789695.n4.nabble.com/BFGS-and-Neldear-Mead-tp3388017p3394334.html Sent

Hello! I´m doing this: A-optim(vv,pen.wlsv,method=BFGS) B-optim(vv,pen.wlsv,method=Nelder-Mead) the function is the same and the initial values too the estimate values are different, very different, at the first decimal is there an error? or maybe its because of my data, or funtion to
