best_poisson_bandit

Description

Compute the Bayesian probabilities for each arm being the best poisson bandit.

Usage

best_poisson_bandit(x, n = NULL)

Arguments

x	as in prop.test, a vector of the number of successes; it may alternatively be a list of vectors of the results of each trial, if n is not provided
n	as in prop.test, a vector of the number of trials; if it is not provided, x must be a list of vectors of the results of each trial

Value

a vector of probabilities for each arm being the best poisson bandit; this can be used for future randomized allocation
