rnonnorm {detectnorm}

Non-normal Distribution

Description

Generating Non-normal data with specified skewness and kurtosis using Fleishman's Method

Usage

rnonnorm(n, mean = 0, sd = 1, skew = 0, kurt = 0)

Arguments

n

number of observations

mean

mean

sd

standard deviation

skew

kurt

kurtosis

Details

This function can be used to generate non-normal data with specified skewness and kurtosis using Fleishman's Power Method.
