The lmomRFA package

Description

R functions for regional frequency analysis using L-moments.

Details

This package implements methods described in the book “Regional frequency analysis: an approach based on L-moments” by J. R. M. Hosking and J. R. Wallis. It is a supplement to the lmom package, which implements L-moment methods for more general statistical applications.

The following functions are contained in this package.

cluagg performs agglomerative hierarchical clustering.

cluinf provides information about cluster membership in a hierarchical clustering.

clukm performs cluster analysis via the K-means algorithm.

reglmr computes a regional weighted average of L-moments.

regsamlmu computes the sample L-moments of multiple data sets.

regtst computes discordancy, heterogeneity and goodness-of-fit measures for regional frequency analysis. These statistics are as described in Hosking and Wallis (1997, chaps. 3-5).

Functions cluagg, cluinf, clukm, reglmr, and regtst are analogous to Fortran routines from the LMOMENTS package, version 3.04, available from StatLib at http://lib.stat.cmu.edu/general/lmoments.
