A Markov chain is called a chain if some power of the transition matrix has only positive elements. In other words, for some n, it is possible to go from any state to any state in exactly n steps. It is clear from this definition that every regular chain is ergodic. floating stairs with glass railing

WebAug 12, 2013 · The OP clearly asks for just a check: I need something to tell that the 'Date' column is a Date type. So how many date classes come with R? Exactly two: Date and POSIXt (excluding their derivatives like POSIXct and POSIXlt). So we can just check on that, and make it more robust than the answers already given: 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
