I have a data set with 925 members that using Easyfit, I've determined is best fit using a Frechet distribution. Now, I'm trying to replicate this functionality in R to determine the optimum fit parameters using the VGAM package. Using this code:
vglm(V1 ~1, frechet2(location = 0), data, trace = FALSE)
I get the following error:
Error in eval(expr, envir, enclos) : initial values for 'location' are out of range
As I'm trying to estimate the 2-parameter distribution the location should be 0 (correct?)
In the VGAM documentation it mentions that the package may fail for low values of shape parameter (near 2 or lower); however, in EasyFit the estimation shows the shape parameter at .2646. Any thoughts on how I should handle this? I've done a search on but haven't found any other packages that provide the same functionality.
Any help would be welcome!
