calculate_sample_means: Calculating sample means from a population

In strboul/mmy: Custom miscellaneous R functions

Description

According to the central limit theorem, the mean of the samples taken from a population would be normally distributed regardless of the distribution of the population.

Usage

calculate_sample_means(x, n, size, replace = FALSE, na.rm = TRUE)

Arguments

x	an atomic numeric vector.
n	number of samples to be taken.
size	sample size to choose.
replace	should sampling done with replacement? default value is FALSE.
na.rm	remove NAs when calculating arithmetic mean. default value is TRUE.

Value

This function takes n number of samples with a size of size and returns a vector with a length of n.

Examples

data <- runif(1e3)
sm <- calculate_sample_means(data, 1e2, 40) # now look at the hist(sm)
