Maximization problem in the optim function
Dear R Users
I am maximizing a user defined log likelihood function. It includes variance
parameter (sigma). I used R function optim with BFGS maximization method.
However, it stops before the solution saying ?sqrt(sigma): NaNs produced?
Could anybody know a proper transformation for sigma which can be passed in
the function? For the correlation parameter I used Fishers? transformation

Specifying Prior Weights in a GLM
...ion. According to R
Documentation in "a binomial GLM prior weights are used to give the number
of trials when the response is the proportion of successes." However when I
run my code I get the following error message:
Error in model.frame.default(formula = PER_ELA ~ A_EX + COMM + ENG + S_R +
:
variable lengths differ (found for '(weights)')
I'm not sure what I am doing wrong. My response variable is Y/M, which is
the proportion of 1's (successes) among M binary responses. My prior weight
is a variable indicating the number of trials for each observation.
