iidspace: Independent Identical Experiments

Description Usage Arguments Details Value Author(s) See Also Examples

Description

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

Usage

1
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.
