varBeta {fcros}

Compute variance of a beta distribution from data

Description

This is an internal function. Given a vector with values between 0 and 1 and assumed to come from a beta distribution, this function return the variance of the distribution. A trim parameter allow to have a robust value

Usage

varBeta(x, trim.opt)

Arguments

x

vector with components between 0 and 1

trim.opt

value between 0 and 0.5 used as trim parameter

Value

This function returns one value equalt to the variance of the best beta distribution of entry x
