loop
I was wondering why this loop doesn't work! for (i in 1:k) fnTr[i] <- function (p) 0.5* sum ( n*log(2*pi) - log(sd(i)^2) +(logitp(i)-p)^2/sd(i)^2 ) outTr[i]<- nlm (fnTr[i],p=c(10),hessian=TRUE) minimumTr[i] <- outTr[i]$minimum valueTr[i] <- outTr[i]$estimate list (minimumTr[i],valueTr[i]) Has anyone can help me? Thank you very much Hathaikan

Loop problem
...equal in colume) fnTr1 <- function (p) sum( n/2*log(2*pi)+log(1/logitTr1$sd)+1/2*(logitTr1$logitp*logitTr1$logitp-2*logitTr1$logitp*p+p^2) *1/logitTr1$sd*logitTr1$sd ) (maximum likelyhood function) outTr1<- nlm (fnTr1,p=c(10),hessian=TRUE) minimumTr1 <- outTr1$minimum valueTr1 <- outTr1$estimate (estimate the value) The problem is the program couldn't work by using logitTr[i],fnTr[i] outTr[i],minimumTr[i],value[i] in a loop. The function logitTr[i] is the data matrix which is not equal each group, fnTr[i] is the maximumlikelyhood function for estimation in next...
