RAB: Compute the relative absolute bias of multiple estimators

Description

Computes the relative absolute bias given the bias estimates for multiple estimators.

Usage

RAB(x, percent = FALSE, unname = FALSE)

Value

returns a vector of absolute bias ratios indicating the relative bias effects compared to the first estimator. Values less than 1 indicate better bias estimates than the first estimator, while values greater than 1 indicate worse bias than the first estimator

Arguments

x

a numeric vector of bias estimates (see bias), where the first element will be used as the reference

percent

logical; change returned result to percentage by multiplying by 100? Default is FALSE

unname

logical; apply unname to the results to remove any variable names?
