Dear list members,
I am trying to use nlm function to maximize a mixture likelihood of beta
densities. There are five unknown parameters in the likelihood. Since I can
get the analytic gradient, I attach the gradient attribute in my target
likehood function. The code is as the following
Oh, that's a typo. I passed the function target. Seems to me R requires
some kind of specific syntex.
