Kurtosis
Computes the kurtosis of the values of x.
If $N = length(x)$, then the kurtosis of $x$ is defined as $$N^(-1) var(x)^(-2) sum_i (x_i - mean(x))^4 - 3$$
Usage
kurtosis(x, na.rm=FALSE)Arguments
- x
- a numeric vector containing the values whose kurtosis is to be computed.
- na.rm
- a logical value indicating whether NA values should be stripped before the computation proceeds.
Value
- Returns the kurtosis of x.
Examples
x<-rnorm(100)
