Fitting distribution with R is something I have to do once in a while.A good starting point to learn more about distribution fitting with R is Vito Ricci's tutorial on CRAN. fitdistrplus: An R Package for Fitting Distributions Abstract: The package fitdistrplus provides functions for fitting univariate distributions to different types of data (continuous censored or non-censored data and discrete data) and allowing different estimation methods (maximum likelihood, moment matching, quantile matching and maximum goodness-of-fit estimation). In the first versions of fitdistrplus, when they were available, the results of the GOF tests (AD, KS, CvM) were automatically printed. In this paper, we present the R package tdistrplus (Delignette-Muller et al., 2014) implementing several methods for tting univariate parametric distribution. Read the documentation about the function integrate(.)
