Re: [R] VGAM package : Frechet distribution - 2 parameter estimation
Hello, a day or two ago I submitted VGAM 0.9-5 to CRAN, which has myriads of changes to family functions---their names, their arguments, and their order thereof. Especially regarding family functions for discrete and continuous distributions. In a nutshell, I found lots of inconsistencies while writing my book, and it was deemed necessary to standardize things. I just had to bite the bullet, so to speak. I have tried to summarize all changes in the NEWS file, however, a few might have gone undocumented. Users of previous versions of VGAM are cautioned to check their code. My apologies for this inconvenience. I have always tried to make it plain that while the version number was less than 1.0-0, everything was subject to change. But the book "Vector Generalized Linear and Additive Models", for Springer, should appear next year, it is synchronized with version 1.0-0, so that should end most of these disruptive changes :) Or at least, curtail them (hopefully). cheers Thomas ps. for this particular problem, only frechet() remains.

Doing ?Frechet (it would be nice to have this aliased also to "frechet") points you immediately to frechet. With "frechet2" substituted for "frechet" your code, everything works. cheers, Rolf Turner On 06/11/14 22:34, Katherine Gobin wrote: Dear Mr Michael, Thanks a lot for your guidance.
