Moment Estimation

This function estimates raw moments around a certain origin or central moments up to a certain degree (r)

Usage

get_moments(x, a, r, na_rm = FALSE, decimal = 3)

Arguments

x

A numeric vector with values of a variable

a

The origin

r

The highest order

na_rm

whether to remove NA; The default value is FALSE

decimal

The no. of digits after decimal

Value

A data frame of r rows and 2 columns; the columns represent order of moment and the moment.

Details

To find the raw moments use the arbitrary origin a, while, for central moments, use a = mean(x).

Examples

x <- sample(10, 5)
get_moments(x, 2, 3) # test r > 0
#>   Order Moment
#> 1     1    4.4
#> 2     2   23.6
#> 3     3  147.2
