biased: Biasing Functions

Description

Some typical biasing functions and inverse functions of the corresponding cumulative biasing functions.

Usage

bs.w.length(x)
  bs.W.length(x)
  bs.w.area(x)
  bs.W.area(x)
  bs.w.invlength(x)
  bs.W.invlength(x)

Arguments

x

vector of observations from the distribution whose density is to be estimated. Missing values are not allowed.

UTF-8

Details

x should be all positive. The bs.W.xxx function is the inverse function of the cumulative biasing function of biasing function bs.w.xxx.
