i want to analyse survival data using typeI HALF LOGISTIC DISTRIBUTION.how can i go about it?it installed one on R in the survival package didn't include the distribution...or i need a code to use maximum likelihood to estimate the parameter in survival analysis.a typical example of distribution other than that installed in R will help.thanks
I am the author of the survival package, and had never heard of the "type I half-logistic" before. New distributions can be added to survreg() if they can be represented as location-scale families; I don't think that your distribution can be written in that way.
Look at "survival" under the "Task Views" tab (upper left corner) of the cran.org web page -- someone else may have already done it.
