Optimization failed in fitting mixture 3-parameter Weibull distri bution using fitdistr()
Dear All;
I tried to use fitdistr() in the MASS library to fit a mixture
distribution of the 3-parameter Weibull, but the optimization failed.
Looking at the source code, it seems to indicate the error occurs at
if (res$convergence > 0)
stop("optimization failed").
The procedures I tested are as following:

cannot write to file
Hello SAMBA Group,
since three days I'm trying to find a solution for my Problem
without any result.
I have a small PC104 PC installed with linux. Ther is no distri-
bution installed but all things I need to start the system, to
login by serial connection or telnet. Now the system must be
connected to my LAN to save some network data. I created the path
/usr/local/samba/bin and put the 'nmbd' ans 'smbd' files in. The
smb.conf is also installed at ../sa...

[Asterisk-Dev] ClueCon in 2 Weeks!
ClueCon is coming in 2 weeks so we urge everyone who plans on
attending to register today so we get a proper headcount!
ClueCon was put together by Asterlink, the same team of people who
helped shape Asterisk into what it is today by writing features,
fixing bugs, offering IRC support and assisting with the management of
the development effort. We have produced several real-world solutions

Using coxph with Gompertz-distributed survival data.
...age must have come across this problem before, so I would like to ask you how you dealt with it. I have set up an illustrative example and included it at the end of this post.
I took a sample of 100 data points from each of two populations ('a' and 'b') known to have Gompertz distributions that differ in both their lambda (initial rate, which is higher in population 'a') and gamma (acceleration rate, which is higher in population 'b') parameters. Each data point represents the age at which an experimental animal died.
First question: given the way the parameters dif...
