Actually I have already done a search on that but it was not much of
a help. That is why I posted it in the r-help in case it was much
more helpful.
There is a tutorial by Ricci with the exact title I suggested looking
for. At the Baron website a search on that quoted string brought up
about 40 hits, most of them relevant, and one of them was from Ricci
with a link to his tutorial. The tutorial has one of its early
examples fitting a Weibull function.

Dear all,
I need to plot an cumulative distribution plot of a variable and
then to fit a distribution to that, probably a weibull or lognormal.
I have plotted the ecdf as
plot(ecdf(x))
but I haven't managed to fit the distribution. I have as well
attached the data.
Try a search on one of the R search sites with:
"Fitting distributions with R" # use the quotes
I would appreciate if you could help me on that.
Thank you.
Kind regards
Maria
