indicatorsbs {bs} | R Documentation |
The function indicatorsbs()
computes the MLE's for alpha, beta, mean, variance, CV, CS and CK for the BSD.
indicatorsbs(x)
x |
Vector of observations. |
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).
The function indicatorsbs()
gives a list of estimations for the alpha, beta, mean, variance, CV,
CS, and CK of BSD.
