Determine recurrece of class in r
Did you know?
WebA positive recurrent state j is always recurrent: If E(τ jj) < ∞, then f j = P(τ jj < ∞) = 1, but the converse is not true: a recurrent state need not be positive recurrent. A recurrent state j for which E(τ jj) = ∞is called null recurrent. Positive recurrence is a communication class property: all states in a communication class
