fitdistrplus 包提供了将单变量分布拟合到不同类型的数据（连续审查或非审查数据和离散数据）的函数，并允许不同的估计方法（最大似然、矩匹配、分位数匹配和最大拟合优度估计）。 fitdist 和 fitdistcens 函数的输出是 S3 对象，为其提供了通用方法，包括摘要、绘图和分位数。该软件包还提供各种函数来比较多个分布与同一数据集的拟合情况，并可以处理参数估计的引导程序。食品风险评估、生态毒理学和保险方面给出了详细的例子。
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). Outputs of fitdist and fitdistcens functions are S3 objects, for which kind generic methods are provided, including summary, plot and quantile. This package also provides various functions to compare the fit of several distributions to a same data set and can handle bootstrap of parameter estimates. Detailed examples are given in food risk assessment, ecotoxicology and insurance contexts.
