Which version of MASS (not that you gave me any credit)? This works in the current 7.1-14. On Tue, 17 Feb 2004, Ernesto Jardim wrote:
I'm trying fitdistr but I'm getting some errors
fitdistr(rnorm(100),"Normal")
Error in fitdistr(rnorm(100), "Normal") : 'start' must be a named list
fitdistr(rnorm(100),"Normal",start=list(mean=0,sd=1))
Error in fitdistr(rnorm(100), "Normal", start = list(mean = 0, sd = 1))
:
supplying pars for the Normal is not supported
What is the problem here ? Am I doing something wrong ?
Hi, I'm using R-1.8.1 with MASS 7.1-13. Sorry for not mentioning MASS.
It was a bug in that version (only, AFAICS -- 7.1-12 required start values). Please update to 7.1-14.
