lmom - Estimating Normal Distribution Parameters using lmom package
Dear R helpers,
I have a data of 2102 observations (consisting of 0's also), to which I am trying to fit Normal distribution using "lmom" pacakage. If I use Excel, its easy to estimate the parameters of Normal distribution as simple mean and standard devaition. The results I get if I use teh excel are as
Parameters of Normal distribution :-
Mean = 22986.44 and standard deviation = 223452.88
However, if I use the R code using the lmom package, I get the mean as 22986.39 and standard deviation as 39029.79.

Estimates at each iteration of optim()?
I am trying to maximise a complicated loglikelihood function with the "optim" command. Is there some way to get to know the estiamtes at each iteration? When I put "control=list(trace=TRUE)" as an option in "optim", I just got the initial and final values of the loglikelihood, number of iterations and whether the routine has converged or not. I need to know the
