Fitting with Beta-prime
Hi, I need to fit my data with beta-prim distribution. I found the function in the package VGAM: betaprime and betaff. I don't know how can I make it work. I know that i need to calculate the parameters that describe this function on my distribution. But for exemple I don't understand the "link function. And then How can I plot my data fitted? Can you help me out with this? Thanks a lot!...
