truncate_dist: Truncation function for normal distributions (truncates both mean and variance)

Description

This function computes the mean and variance of a normal distributions that has been truncated at one or both ends.

Usage

truncate_dist(a = -Inf, b = Inf, mean = 0, sd = 1)

Value

A matrix of truncated means (column 1) and truncated variances (column 2).

Arguments

a

Quantile (i.e., cut score) below which scores should be censored from the distribution.

b

Quantile (i.e., cut score) above which scores should be censored from the distribution.

mean

Scalar mean or vector of means.

sd

Scalar standard deviation or vector of standard deviations.

Examples

truncate_dist(a = -1, b = 3, mean = 0, sd = 1)
truncate_dist(a = 1, b = Inf, mean = 0, sd = 1)
truncate_dist(a = c(-1, 1), b = c(3, Inf), mean = 0, sd = 1)
