Error in optim while using fitdistr() function for estimation of parameters
...nitial value in 'vmmin' is not finite What should I do ? I need this function because I want to get value of estimated parameters. Is there any other function to perform such calculations? Please help me. Thank You. Code is as follows: x<-data.frame() N<-data.frame((read.table("cs2ip.txt"))) attach(N) library(MASS) fd<-fitdistr(V2,"gamma") Aswad [[alternative HTML version deleted]]
