discreteRV (version 1.2.2)

Create and Manipulate Discrete Random Variables

Description

Create, manipulate, transform, and simulate from discrete random variables. The syntax is modeled after that which is used in mathematical statistics and probability courses, but with powerful support for more advanced probability calculations. This includes the creation of joint random variables, and the derivation and manipulation of their conditional and marginal distributions.

Functions in discreteRV (1.2.2)

Variance of a random variable

Tests whether the random variables X and Y are independent

Marginal distribution of a joint random variable

Turn a probability vector with possible outcome values in the 'names()' attribute into a random variable:

Make a joint random variable consisting

Kurtosis of a random variable

Calculate probabilities of events

Marginal distributions of a joint random variable

Joint probability mass function of random variables X and Y

Print a random variable of class "RV"

Skewness of a random variable

Skew of the empirical distribution of simulated data

Normal quantile plot for RVs to answer the question how close to normal it is

Plot a random variable of class "RV"

Proportions of observed outcomes in one or more vectors of simulated trials

Proportion of an event observed in a vector of simulated trials

Compute the logical OR of two events

Compute the logical AND of two events

Make a random variable consisting of possible outcome values and their probabilities or odds

Probability mass function of X^n

Simulate n independent trials from a random variable X:

Sum of independent random variables
