[R] mle question

2011-02-01 Thread Antje Niederlein
Hello, I tried to use mle to fit a distribution(zero-inflated negbin for count data). My call is very simple: mle(ll) ll() takes the three parameters, I'd like to be estimated (size, mu and prob). But within the ll() function I have to judge if the current parameter-set gives a nice fit or not.

[R] mle() question

2009-05-22 Thread Stephen Collins
Is there a way to code the mle() function in library "stats4" such that it switches optimizing methods midstream (i.e. BFGS to Newton and back to BFGS, etc.)? Thanks, Stephen Collins, MPP | Analyst Health & Benefits | Aon Consulting [[alternative HTML version deleted]] __
