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")
::install_github("aursiber/fitdistrplus") remotes
Finally load the package in your current R session with the following R command:
library(fitdistrplus)
Three vignettes are attached to the
fitdistrplus
package:
