Fitting Mixed Distributions in the fitdistrplus package
Dear Sirs, The below listed code fits a gamma and a pareto distribution to a data set danishuni. However the distributions are not appropriate to fit both tails of the data set hence a mixed distribution is required which has ben defined as "mixgampar" as shown below. library(fitdistrplus) x<- danishuni$Loss fgam<- fitdist(x,"gamma",lower=0) fpar<- fitdist(x,"pareto",start = list(shape=2,scale=2),lower=0) fmixgampar<- fitdist(x,"mixgampar",start = list(prob=1/2,nu=1,lambda=1,alpha=1,theta=1),lowe...
