var.p {GE}

Population Variance and Population Standard Deviation

Description

The function var.p computes a population variance. The function sd.p computes a population standard deviation.

Usage

var.p(x, wt = rep(1, length(x)), na.rm = FALSE)

sd.p(x, wt = rep(1, length(x)), na.rm = FALSE)

Arguments

x

a numeric vector.

wt

a numeric vector of weights. By default all elements of x are given the same weight.

na.rm

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

Functions

• var.p: Population variance.

• sd.p: Population standard deviation.

Examples

var.p(1:6)

var.p(x = 1:5, wt = 6:10)
var.p(x = rep(1:5, 6:10))

sd.p(x = 1:5, wt = 6:10)
sd.p(x = rep(1:5, 6:10))
