Hi, 

 

I tried to calculate the MLE estimation of a parameter of a gamma
distribution of a data set, which is called "amount".. I did it with the
command: fitdistr(amount,"gamma") 

and got the error message:

Error in optim(x = c(363.36, 551.15, 603.91, 170.99, 225.21, 218.01,
1816.82,  : 

        non-finite finite-difference value [2]

Warning message:

NaNs wurden erzeugt in: dgamma(x, shape, scale, log)

 

What does it mean? What can I do?

 

Kind regards, 

Oliver
