The

Probabilitiesworksheet computes and displays the n-step transition matrix. TheStartbutton sets the matrix to equal the transition matrix defined on the Matrix worksheet. TheMorebutton, provides subsequent n-step transition matrices. The example below shows the 3-month transition matrix for the light bulb case. An entry in rowicolumnjgives the probability of a transition from stateito statejin three steps. To illustrate, the row for 2-mo. gives the probability distribution for the age of the bulb at some location, given that the bulb was 2 months old at the location at the beginning of a three month period.
