=== fitdistrplus : Help to fit of a parametric distribution === Version 0.3-4 ============= NEW FEATURES - posibility to fix xlegend to a keyword (e.g. "bottomright") in "cdfcomp" and "cdfcompdens" - improvement of the new vignette BUG FIXES - correction of the NAMESPACE file in order to enable the correct print of a summary of a fitdistcens object (with the correlation matrix, the loglikelihood and AIC and BIC statistics) Version 0.3-3 ============= NEW FEATURES - a new function ("cdfcompcens") to plot cumulative distributions corresponding to various fits using a same censored data set. - add an example with scaling problem in man pages. Version 0.3-2 ============= NEW FEATURES - new plot of the empirical cdf curve in plotdistcens, using the Turnbull algorithm by a call to function survfit{survival} - new arguments to function "cdfcomp" : verticals, horizontals and xlim Version 0.3-1 ============= NEW FEATURES - add of a draft of a new version of the vignette Version 0.3-0 ============= NEW FEATURES - a new function ("cdfcomp") to plot cumulative distributions corresponding to various fits using a same non censored data set. - add of two data sets : "endosulfan" and "toxocara". Version 0.2-2 ============= BUG FIXES - elimination of NON-ASCII characters in the vignette. Version 0.2-1 ============= NEW FEATURES - a new fitting method was implemented for continuous distributions : the maximum goodness-of-fit estimation (function "mgedist") (for the moment only available for non censored data). Version 0.1-5 ============= NEW FEATURES - a new goodness-of-fit statistic was added in gofstat, with corresponding test : the Cramer-von Mises distance - a new fitting method has been implemented : the quantile matching estimation (function "qmedist"). For the moment, only available for non censored data. - the moment matching estimation has been extended (in function mmedist) to enable numerical matching when closed formula are not available. BUG FIXES - correction of a bug inserted while adding the argument "fix.arg" which prevent the print of the results of goodness-of-fit tests . Version 0.1-4 ============= NEW FEATURES - a component named dots added to the list returned by fitdist and fitdistcens in order to pass optional arguments for the control of optimization in mledist to bootdist and bootdistcens. bootdist and bootdistcens changed to take into account these optional arguments if they are defined in the call to fitdist or fitdistcens. - an argument added to fitdist, fitdistcens and mledist, named fix.arg, and giving the possibility to fix some of the distribution parameters while maximizing the likelihood. Functions bootdist, bootdistcens and gofstat were also changed in order to take this new argument into account. - a new data file of bacterial contamination censored data extracted from Busschaert et al. 2000 and examples corresponding to analysis of this dataset. BUG FIXES - correction of a bug in the print and the plot of boostraped samples using bootdist or bootdistcens when there was only one parameter estimated by maximum likelihood. Version 0.1-3 ============= NEW FEATURES - new data file "groundbeef" (groundbeef.rda and groundbeef.Rd) and new use of this dataset in some examples. - new function gofstat. Goodness-of-fit statistics are no more computed by fitdist but may computed and printed by the use of the function gofstat. In this new function, the whole results computed are not printed : results of tests are printed only if the argument print.test==TRUE and for continuous distributions only Anderson-Darling and Kolomogorov-Smirnov statistics are printed by default (but complete results are returned by gofstat). - modifications in descdist : three arguments were added in descdist 1/ method, to choose between unbiased estimations of standard deviation, skewness and kurtosis (default choice) and sample values. 2/ obs.col to choose the color used to plot the observed point on the graph. 3/ boot.col to choose the color used to plot the bootstrap sample of points on the graph. - modifications in plotfit : minor changes were performed in order to facilitate the use of the argument ... to personnalize the plots (see examples in plotdist.Rd) - modication of the vignette BUG FIXES - correction of a bug in plotdist due to the redefinition in the previous version of the parameter "ylim" for the plot of a histogram with theoretical density function (there was a problem with infinite values of theoretical density function) Version 0.1-2 ============= NEW FEATURES - deletion of mledistcens and modification of mledist in order to maximize likelihood for both censored and non censored data. - possibility to choose the optimization method used for maximum likelihood estimation (MLE) of distribution parameters using the new argument "optim.method" of mledist. - possibility to specify contraints on distribution parameters using the new arguments "lower" and "upper" of mledist. - possibility to use a custom optimization function for MLE using the new argument "custom.optim". - moment matching estimation is no longer done with argument method set to "mom" but set to "mme" in fitdist. - renaming of momdist in mmedist. - calculation of AIC and BIC criterion after maximum likelihood estimation of distribution parameters - change of the default number of iterations from 999 to 1001 for boostrap in order to avoid interpolation using the quantile function - use of the argument "log" and (resp. "log.p") of density (resp. distribution) when available to compute the loglikelihood. BUG FIXES - omitting the name of the first argument in calls to the density function during maximization of the likelihood in order to enable the use of a density function defined with a first parameter (the vector of quantiles) with a name differing from "x" (classical name for density distributions defined in R), such as the density function dexGAUS from the package gamlss.dist. Version 0.1-1 ============= - Initial release.
