PopulationStat: Population statistics

Description

Computes theoretical descriptive statistics of a distribution.

Usage

populationstat(stat = "mean", dist, distarg, p0 = 0, distbounds = c(-Inf, Inf))
popmean(dist, distarg, p0 = 0, distbounds = c(-Inf, Inf))
popsd(dist, distarg, p0 = 0, distbounds = c(-Inf, Inf))
popvar(dist, distarg, p0 = 0, distbounds = c(-Inf, Inf))
popcvar(dist, distarg, p0 = 0, distbounds = c(-Inf, Inf))
popskew(dist, distarg, p0 = 0, distbounds = c(-Inf, Inf))
popkurt(dist, distarg, p0 = 0, distbounds = c(-Inf, Inf))

Value

scalar numeric

Arguments

stat

character; statistic to compute — one of "mean", "sd", "var", "cvar", "skew", "kurt"

dist

character; distribution name (e.g. "norm", "paretoII")

distarg

list of distribution arguments

p0

numeric; probability zero (default 0)

distbounds

numeric vector of length 2; distribution bounds (default c(-Inf, Inf))
