LMoments.Rd

Calculates the Lmoments and Lmoment ratios from a sample of data

Usage

LMoments(x)

Arguments

x

a numeric vector. The sample of interest

Value

A data.frame with one row and column headings; L1, L2, L3, L4, Lcv, LSkew, and LKurt. The first four are the Lmoments and the next three are the Lmoment ratios.

Details
