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.
