kurtosis | R Documentation |
This function computes the theoretical and empirical values of three indices of kurtosis.
kurtosis(x = NULL, p, value = c("estimate", "parameter"))
x |
A sample of observations. |
p |
the shape parameter. |
value |
If is set to |
It returns the vector of the three indices of kurtosis VI
, \beta_2
and \beta_p
.
Giving a vector as argument, it returns the estimates of the three indices, computed on the sample.
On the other hand, giving the value of the shape parameter p
, it returns the theoretical indices.
