expectation.poisson_dist: Exact expectation for a Poisson distribution.
In algebraic.dist: Algebra over Probability Distributions
expectation.poisson_dist R Documentation
Exact expectation for a Poisson distribution.
Description
Computes E[g(X)] using truncated summation over the support.
The summation is truncated at the 1 - 10^{-12} quantile to
ensure negligible truncation error.
Usage
## S3 method for class 'poisson_dist'
expectation(x, g, ...)
Arguments
x
A poisson_dist object.
g
A function to take the expectation of.
...
Additional arguments passed to g.
Value
The expected value E[g(X)].
Examples
x <- poisson_dist(5)
expectation(x, identity)
expectation(x, function(k) k^2)
