In algebraic.dist: Algebra over Probability Distributions

Method for obtaining the expectation of f with respect to a univariate_dist object x.

Description

Assumes the support is a contiguous interval that has operations for retrieving the lower and upper bounds.

Usage

## S3 method for class 'univariate_dist'
expectation(x, g, ..., control = list())

Arguments

x	The distribution object.
g	The function to take the expectation of.
...	Additional arguments to pass into g.
control	An (optional) list of control parameters for integrate or expectation_data (if x is not continuous)

Value

The expected value (numeric scalar), or the full integrate() result if compute_stats = TRUE.

Examples

x <- normal(3, 4)
# E[X] for Normal(3, 4) is 3
expectation(x, function(t) t)

# E[X^2] for Exp(1) is 2
expectation(exponential(1), function(t) t^2)
