kurtosis {normalp} | R Documentation |
This function computes the theoretical and empirical values of three indexes of kurtosis.
kurtosis(x, p=3, value="parameter")
x |
A sample of observations. |
p |
the structure parameter. |
value |
If is set to estimate , evaluate the indexes using an estimate of p.
Otherwise, if is set to parameter it uses the value specified in p . |
It returns the vector of the three indexes of kurtosis VI, Beta2 and Betap. Giving a vector as argument, it returns the estimates of the three indexes, computed on the sample. On the other hand, giving the value of the structure parameter p, it returns the theoretical indexes.
