Normal distribution {dprop} | R Documentation |
Compute the distributional properties of the normal distribution
Description
Compute the first four ordinary moments, central moments, mean, and variance, Pearson's coefficient of skewness and kurtosis, coefficient of variation, median and quartile deviation based on the selected parametric values of the normal distribution.
Usage
d_normal(alpha, beta)
