To my great embarrassment it was brought to my attention that one of the results in my paper which appeared in this journal in June 1991 duplicated work which originally had been presented by Jeffrey J. Hunter in a much earlier paper. His paper has a hauntingly familiar title: Generalized inverses and their application to applied probability problems, and appeared in Linear Algebra and Its Applications, Volume 45 (1982). His paper presented, for the first time, a formula for the stationary distribution which was based on a generalized inverse. An equivalent formula was erroneously presented as a new result in Section 2 of my paper. Several of my results were similar to, though different from, other results in both this paper and his later 1986 paper (see below). While my results were new in this case, there should have been a reference to this earlier work. Professor Hunter has written several papers about the generalized inverses related to Markov chains; below is a partial list.
