fitdistrplus
extends the fitdistr()
function (of the MASS
package) with several functions to help the fit of a parametric distribution to non-censored or censored data. Censored data may contain left censored, right censored and interval censored values, with several lower and upper bounds. In addition to maximum likelihood estimation (MLE), the package provides moment matching (MME), quantile matching (QME) and maximum goodness-of-fit estimation (MGE) methods (available only for non-censored data). Weighted versions of MLE, MME and QME are available.
The stable version of fitdistrplus
can be installed from CRAN using:
install.packages("fitdistrplus")
The development version of fitdistrplus
can be installed from GitHub (remotes
needed):
if (!requireNamespace("remotes", quietly = TRUE))
install.packages("remotes")
remotes::install_github("aursiber/fitdistrplus")
Finally load the package in your current R session with the following R command:
library(fitdistrplus)
Three vignettes are attached to the fitdistrplus
package:
