kurtosis {AMR} | R Documentation |
Kurtosis of the Sample
Description
Kurtosis is a measure of the "tailedness" of the probability distribution of a real-valued random variable. A normal distribution has a kurtosis of 3 and a excess kurtosis of 0.
Usage
kurtosis(x, na.rm = FALSE, excess = FALSE)
## Default S3 method:
kurtosis(x, na.rm = FALSE, excess = FALSE)
## S3 method for class 'matrix'
kurtosis(x, na.rm = FALSE, excess = FALSE)
## S3 method for class 'data.frame'
kurtosis(x, na.rm = FALSE, excess = FALSE)
Arguments
x |
A vector of values, a matrix or a data.frame. |
na.rm |
A logical to indicate whether |
excess |
A logical to indicate whether the excess kurtosis should be returned, defined as the kurtosis minus 3. |
