[R] MLE for noncentral t distribution

2008-05-08 Thread kate
I have a data with 236 observations. After plotting the histogram, I found that it looks like non-central t distribution. I would like to get MLE for mu and df. I found an example to find MLE for gamma distribution from fitting distributions with R: library(stats4) ## loading package stats4

QRMlib has routines for fitting t distributions. Have a look at that package. Also sn has routines for skew-t distributions David Scott On Thu, 8 May 2008, kate wrote: I have a data with 236 observations. After plotting the histogram, I found that it looks like non-central t
