Methods

Methods for interacting with distributions.

Probability functions

density(<distribution>) stable

The probability density/mass function

quantile(<distribution>) stable

Distribution Quantiles

generate(<distribution>) stable

Randomly sample values from a distribution

Summary statistics

mean(<distribution>) stable

Mean of a probability distribution

median(<distribution>) stable

Median of a probability distribution

variance() covariance(<numeric>) stable

Variance

variance(<distribution>) stable

Variance of a probability distribution

covariance() stable

Covariance

covariance(<distribution>) stable

Covariance of a probability distribution

skewness() stable

Skewness of a probability distribution

kurtosis() stable

Kurtosis of a probability distribution

likelihood() log_likelihood() stable

The (log) likelihood of a sample matching a distribution
