Hello!
I need to perform maximum likelihood estimation on R, but I am not sure
which command to use. I searched on google, and found an example using the
function mlogl, but I couldn't find the package on R. Is there such
function? Or how should i perform my mle?
Thank you very much.

Using the inverse logistic transform to replace p by exp(xp)/(1+exp(xp)) allows
unconstrained fitting of xp. There may still be problems where xp tends to + or
- infinity depending on starting values.

Thanks, but when I use L-BFGS-B it tells me that there is an error in

Hi Guys, it would be great if you could help me with a MLE problem in R.
I am trying to evaluate the maximum likelihood estimates of theta = (a1,
b1, a2, b2, P) which defines a mixture of a Poisson distribution and two
gamma prior distributions (where the Poisson means have a gamma
distribution,

Excellent, also the book:

Is very good and the associated Web Site is full of MLE using R.

(which, BTW, uses optim() underneath.)
Also, for those not aware of it, fitdistr(x, "normal") just computes mean(x)
and (n-1)/n * var(x) and return them. (I can't imagine any reason to do
otherwise for normal distribution.)

If, however, you are more interested in general methods for
maximizing a likelihood function, I suggest you look at "optim", work

Well, lm() produces an OLS solution, which are also MLE solutions for the
fixed effects. I think this is an easy way, although maybe not the best.
