Details. 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). For the Normal, log-Normal, geometric, exponential and Poisson distributions the closed-form MLEs (and exact standard errors) are used, and start should not be supplied.. For all other distributions, direct optimization of the log-likelihood is performed using optim.The estimated standard errors are taken from the observed information matrix, calculated by a numerical approximation. In some cases, other estimation methods could be pref-ered, such as maximum goodness-of- t estimation (also called minimum distance estimation), as proposed in the R package actuar with three di erent goodness-of- t distances (Dutang, Goulet, and Pigeon2008). We decided to suppress this automatic printing when we realized that some users had some difficulties to interpret the … While developping the tdistrplus package, a second objective was to consider various estimation methods in addition to maximum likelihood estimation (MLE). In this paper, we present the R package tdistrplus (Delignette-Muller et al., 2014) implementing several methods for tting univariate parametric distribution.
