quantileTPS | R Documentation |
Computes the sample quantiles of a time-persistent function, corresponding to the given probabilities.
quantileTPS(times = NULL, numbers = NULL, probs = c(0, 0.25, 0.5, 0.75, 1))
times |
A numeric vector of non-decreasing time observations |
numbers |
A numeric vector containing the values of the time-persistent statistic between the time observation |
probs |
A numeric vector of probabilities with values in [0,1] |
The lengths of \code{times} and \code{numbers} either must be the same, or \code{times} may have one more entry than \code{numbers} (interval endpoints vs. interval counts). The sample quantiles are calculated by determining the length of time spent in each state, sorting these times, then calculating the quantiles associated with the values in the \code{prob} vector in the same fashion as one would calculate quantiles associated with a univariate discrete probability distribution.
