iidspace: Independent Identical Experiments

In aflaherty13/prob: Elementary Probability on Finite Sample Spaces

Description

Sets up a probability space corresponding to independent, identical experiments.

Usage

iidspace(x, ntrials, probs = NULL)

Arguments

x	a vector of outcomes.
ntrials	number of times to perform the experiment.
probs	vector of non-negative weights corresponding to x.

Details

The elementary experiment to be repeated consists of drawing an element of x according to the probabilities contained in probs. The entries of probs need not sum to one, but they will be normalized before any computations. If probs is not specified, the equally likely model will be assumed.

Value

A data frame, with a probs column, where probs is calculated to be the probability of observing the outcome in its row under the assumption of independence and identical distribution of draws from x.

iidspace( 1:6, ntrials = 3) # same as rolldie(3)
iidspace( 1:6, ntrials = 3, probs = 3:8 ) # unbalanced die
