Hi,
How to fit data to cumulative normal distribution?
I tried such way:
library(MASS)
ed<-c(1:10)
cnd<-function(mn,sdd){pnorm(c(1:10),mn,sdd)}
fitdistr(ed,cnd,start=list(mn=mean(ed),sdd=sd(ed)))
.but an error occured:
Error in solve.default(res$hessian) :
function Lapack 'dgesv': system are exactly singular
Thank you for help
