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

Random effect model
Dear R-help group,
I would like to model directly following random effect model:
Y_ik = M_ik + E_ik where M_ik ~ N(Mew_k,tau_k^2)
E_ik ~ N(0,s_ik^2)
i = number of study
k = number of treatment
---------------------------------------------------------------------------
I have practiced using the command from 'Mixed -Effects models in S and
S-plus'

Loop problem
Dear everyone
I am a new user,would like to combine these code together by using a
loop,each function has three value as Tr = 1 - 3,how can i combine
together?
logitTr1 <-logit[logit[,"Study"]&logit[,"Tr"]==1,]
(number of row in each group (1-3) is difference but equal in colume)
fnTr1 <- function (p) sum(
