Similarly, if we raise transition matrix T to the nth power, the entries in T n tells us the probability of a bike being at a particular station after n transitions, given its initial station. And if we multiply the initial state vector V 0 by T n , the resulting row matrix Vn=V 0 T n is the distribution of bicycles after \(n\) transitions.P (new=C | old=D) P (new=D | old=D) I can do it in a manual way, summing up all the values when each transition happens and dividing by the number of rows, but I was wondering if there's a built-in function in R that calculates those probabilities or at least helps to fasten calculating those probabilities.Using this method, the transition probability matrix of the weather example can be written as: The rows represent the current state, and the columns represent the future state.

For long times restricting to first order is a poor approximation and one should include higher order terms. A sign that keeping only the first order term is poor is precisely that the transition probability becomes unphysically greater than 1.
