Sojourn times

Source: R/passage.R
sojourn_time.Rd

The expected number of consecutive periods a unit remains in a class before leaving it, \(1 / (1 - p_{ii})\) for each class \(i\). Large values indicate "sticky" classes with strong persistence.

Usage

sojourn_time(x, ...)

# Default S3 method
sojourn_time(x, ...)

# S3 method for class 'sddr_markov'
sojourn_time(x, ...)

Arguments

x

A row-stochastic matrix, or an object of class sddr_markov.

...

Currently unused.

Value

A named numeric vector of sojourn times (one per class). Absorbing classes (\(p_{ii} = 1\)) return Inf.
