BootCoefQuartVar: R6 Bootstrap Resampling for Coefficient of Quartile Variation

Description

The R6 class BootCoefQuartVar produces the bootstrap resampling for the coefficient of quartile variation (cqv) of the given numeric vectors. It uses boot from the package boot. Also, it produces the bootstrap confidence intervals for the cqv based on the boot.ci from the package boot.

Arguments

x

An R object. Currently there are methods for numeric vectors

na.rm

a logical value indicating whether NA values should be stripped before the computation proceeds.

alpha

The allowed type I error probability

R

integer indicating the number of bootstrap replicates.
