Sets up a probability space corresponding to independent, identical experiments.
iidspace(x, ntrials, probs = NULL)
a vector of outcomes.
number of times to perform the experiment.
vector of non-negative weights corresponding to x
.
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
.
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.
# NOT RUN {
iidspace( 1:6, ntrials = 3) # same as rolldie(3)
iidspace( 1:6, ntrials = 3, probs = 3:8 ) # unbalanced die
# }
