Random Variable From a t Distribution — rt

Generate random numbers from a t distribution, rescaled to have user-specified population mean and standard deviation.

Usage

rt_rs(n = 10, df = 5, pmean = 0, psd = 1)

Arguments

n: The number of random numbers to generate.
df: df for stats::rt().
pmean: Population mean.
psd: Population standard deviation.

Value

A vector of the generated random numbers.

Details

First, specify the parameter df and the desired population mean and standard deviation. The random numbers, drawn from the generalized normal distribution by stats::rt(), will then be rescaled with the desired population mean and standard.

Examples

set.seed(90870962)
x <- rt_rs(n = 5000,
           df = 5,
           pmean = 3,
           psd = 1)
mean(x)
#> [1] 3.004783
sd(x)
#> [1] 0.9926204
hist(x)
