Hello, The value for 'start' is not correct. According to the help for "fitdistr", 'start' should contain the paramaters used by the random function (?rchisq) Hope this helps, Pascal

I generated some random data using R and then trying to see if it came from
the same distribution but the erros keep piling. Can anyone help?
y=rchisq(100000,1)
mean(y)
var(y)
library(MASS)
fitdistr(y, "chi-squared", start = list(4), method = "Brent", lower=0.9,
upper=3)

Thanks,
