The function var.p computes a population variance. The function sd.p computes a population standard deviation.
var.p(x, wt = rep(1, length(x)), na.rm = FALSE)sd.p(x, wt = rep(1, length(x)), na.rm = FALSE)
sd.p(x, wt = rep(1, length(x)), na.rm = FALSE)
a numeric vector.
a numeric vector of weights. By default all elements of x are given the same weight.
a logical value indicating whether NA values should be stripped before the computation proceeds.
