Even if you can get a p-value, it cannot tell you that. 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). endobj We use analytics cookies to understand how you use our websites so we can make them better, e.g. Maximum likelihood estimations of the distribution parameters are computed using the function mledist. By default direct optimization of the log-likelihood is performed using optim,with the "Nelder-Mead" method for distributions characterized by more than one parameterand the "BFGS" method for distributions characterized by only one parameter. Censored data may contain left censored, right censored and interval censored values, with several lower and upper bounds. While developping the tdistrplus package, a second objective was to consider various estimation methods in addition to maximum likelihood estimation (MLE). 2 tdistrplus: An R Package for Fitting Distributions posed in the R package actuar with three di erent goodness-of- t distances (Dutang, Goulet, and Pigeon2008). 2 tdistrplus: An R Package for Fitting Distributions tion from a general point-of-view.

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. >> Zeileis    ISSN 1548-7660; CODEN JSSOBK, Creative Commons Attribution 3.0 Unported License, Marie Laure Delignette-Muller, Christophe Dutang. 62 0 obj << I'm using the fitdist() function from the package fitdistrplus . /Filter /FlateDecode Examples See mledist, mmedist, qmedist, mgedist, msedist for details on parameter estimation.
