dst_finite: Create a Finite Distribution

In vincenzocoia/distionary: Create and Evaluate Univariate Probability Distributions

Create a Finite Distribution

Description

A finite distribution assigns probabilities to a finite collection of values. This includes categorical distributions.

Usage

dst_finite(y, probs, data, ...)

Arguments

y	<data-masking> Outcomes to comprise the distribution. Should either evaluate to an (atomic) vector, or be a name in the specified data.
probs	<data-masking> Probabilities corresponding to the outcomes in y. Must not be negative, but must sum to 1 (unlike dst_empirical()). Should either evaluate to a vector, or be a name in the specified data.
data	Data frame containing the outcomes y and/or probabilities probs. Optional.
...	Additional arguments, currently not used.

Value

An object of class c("finite", "dst").

Note

This distribution is called "finite" and not "discrete", because a discrete distribution could have an infinite amount of possible outcomes, as in the Poisson distribution.

Examples

dst_finite(1:5, probs = rep(0.2, 5))
