Hi!
Recently I try to find the method maximum
likelihood for gamma,weibull,Pearson type III,Kappa Distribution,
mixed exponential distribution, skew distribution.
I have tried function ms() for gamma two parameters and weibull two
parameters.It works but not for Pearson type III. I have problem to
I suggest you go to "www.r-project.org" -> CRAN -> (select a local
mirror) -> Packages. Among the offerings there, you will find the
following:

distrEx Extensions of package distr

I bet your friend was really angling for that.

Hi,
I'm dealing with wind data and I'd like to model their distribution in
order to simulate data to fill-in missing values. Wind direction are
typically following a vonmises distribution and wind speeds follow a
weibull distribution. I'd like to build a joint distribution of
directions and speeds

the choice of the copula is, in fact, a model selection problem.
First, you could have a look at the contour plots of different copulas
