skew: Calculate skew or kurtosis for a vector, matrix, or data.frame
Description
Find the skew and kurtosis for each variable in a data.frame or matrix. Unlike skew and kurtosis in e1071, this calculates a different skew for each variable or column of a data.frame/matrix.
Usage
skew(x, na.rm = TRUE)
kurtosi(x, na.rm = TRUE)
Arguments
x
A data.frame or matrix
na.rm
how to treat missing data
Value
if input is a matrix or data.frame, skew (kurtosi) is a vector of skews (kurtosi)
Details
given a matrix or data.frame x, find the skew or kurtosis for each column.
