kurtosis: Kurtosis

Description

Functions to compute kurtosis.

Usage

kurtosis(x, ...)
## S3 method for class 'default':
kurtosis(x, na.rm = FALSE, method = c("excess", "moment", "fisher"), ...)
## S3 method for class 'data.frame':
kurtosis(x, \dots)
## S3 method for class 'POSIXct':
kurtosis(x, \dots)
## S3 method for class 'POSIXlt':
kurtosis(x, \dots)

Arguments

na.rm

a logical. Should missing values be removed?

method

a character string which specifies the method of computation. These are either "moment", "fisher", or "excess". If "excess" is selected, then the value of the kurtosis is compu

x

a numeric vector or object.

...

arguments to be passed.

Value

• kurtosis returns the value of the statistics, a numeric value. An attribute which reports the used method is added.
