Hi, I am looking for some help regarding the use of the mle function.
I am trying to get mle for 3 parameters (theta0, theta1 and theta2) that have been defined in the the log-likelihood equation as theta0=theta[1], theta1=theta[2] and theta2=theta[3]. My R code for mle is: mle(Poisson.lik, start=list(theta=c(20,1,1), method="Nelder-Mead", fixed=list(w=w, t1=t1, t2=t2)) But I keep getting the following error, Error in eval(expr, envir, enclos) : argument is missing, with no default I am trying to maximise theta starting at (20,1,1) over a fixed range of w, t1 and t2. Can anyone shed some light as to what is going on?
