Indicators for the Birbaum-Saunders distribution

Description

The function indicatorsbs() computes the MLE's for alpha, beta, mean, variance, CV, CS and CK for the BSD.

Usage

indicatorsbs(x)

Arguments

x Vector of observations.

Details

By using the invariance property of the MLE's, we obtain estimations for the mean, the variance, and the coefficients of variation (CV), skewness (CS), and kurtosis (CK).

Value

The function indicatorsbs() gives a list of estimations for the alpha, beta, mean, variance, CV, CS, and CK of BSD.
