## List of functions

This is a set of Maxima functions for probability distributions, both continuous and discrete.

For every probability distribution, a set of functions are defined. The asterisks in the following list must be substituted by the name of the distribution:

**pdf_***: Probability density function
**cdf_***: Cumulative distribution function
**quantile_***: Quantile
**mean_***: Mean
**var_***: Variance
**std_***: Standard deviation
**skewness_***: Skewness coefficient
**kurtosis_***: Kurtosis coefficient
**random_***: Random variate

The names of the continuous distributions follow. Asterisks must be substituted by the names of the functions in the list above:

***normal**: Normal
***student_t**: Student
***chi2**: Chi^2
***f**: F
***exp**: Exponential
***lognormal**: Lognormal
***gamma**: Gamma
***beta**: Beta
***continuous_uniform**: Continuous uniform
***logistic**: Logistic
***pareto**: Pareto
***weibull**: Weibull
***rayleigh**: Rayleigh
***laplace**: Laplace
***cauchy**: Cauchy
***gumbel**: Gumbel
***noncentral_chi2**: Noncentral Chi^2
***noncentral_student_t**: Noncentral Student

List of discrete distributions:

***binomial**: Binomial
***poisson**: Poisson
***bernoulli**: Bernoulli
***geometric**: Geometric
***discrete_uniform**: Discrete uniform
***hypergeometric**: Hypergeometric
***negative_binomial**: Negative binomial
***general_finite_discrete**: Finite discrete

In case of the Cauchy distribution, there are no functions for the mean, variance, skewness and kurtosis coefficients.

Inside Maxima, type **describe(function_name)$** to read the documentation on any function.
