In NVE/fitdistrib: A list a functions to fit data to probability distributions

# R output pre blocks are styled by default to indicate output

rdl <- function(x) packagedocs::rd_link(deparse(substitute(x)))

What is the fitdistrib package?

This package is a set a functions developed with the FlomKart flood frequency analysis project at NVE. It allows estimating probability distribution parameters for the following distributions:

• GEV: Generalized Extreme Value
• GL: Generalized Logistics
• PEARSON: Three parameter Pearson distribution
• GAMMA distribution
• GUMBEL distribution

Four different estimation methods are available:

• MOM: method of moments
• Lmom: linear moments
• MLE: Maximum Likelyhood Estimation
• Bayes: Bayesian inference

The results of this package are used in the FlomKartpackage (documentation and code) to build 2 NetCDF files which can then be explored with the NASA's NetCDF viewer [Panoply](http://www.giss.nasa.gov/tools/panoply/) or by our dedicated FlomKart shiny app (documentation and code).

How was it coded?

In Package Ref, you'll find the documentation of all the packaged functions. This package uses the existing R packages nsRFA, evd, ismev, fitdistrplus and stats. The use of functions from those packages is adapted to our context. Some new fitting functions were also implemented when not already available.
