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 find the likelihood function for mixed exponential distribution and kappa distribution. So can anyone tell me the programming for those functions? especially in finding their maximum likelihood,because I have trouble to write down the likelihood function for mixed exponential distribution and the other two.If possible ,how to get the hessian matrix? Currently I am using SPlus 6.2.
Thanks. suhaila ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
