Textbook Question
Chapter 8.3, Problem 1CYU
When an absorbing stochastic matrix is partitioned, the submatrix in the upper left is an identity matrix, denoted by I. Also, when finding the stable matrix, we subtract the submatrix R from an identity matrix, also denoted by I. Are these two identity matrices the same size?
