Webmatrix M. In fact, for any transition matrix that can be written in the form (9),the broadcast process is non-reconstructible. We simulate the broadcast on d−ary tree T = {V,E}with root node ζ ∈Ω as a λ-percolation process. Note that we use the transition matrix M, which means that the probability of from ito jis M i,j. Hence we can ... WebYou have 4 states: S = { 1 := A, 2 := B, 3 := C, 4 := D }. Let n i j be the number of times the chain made a transition from state i to state j, for i j, = 1, 2, 3, 4. Compute the n i j 's from your sample and estimate the transition matrix ( p i j) by maximum likelihood using the estimates p ^ i j = n i j / ∑ j = 1 4 n i j. – Sep 11, 2012 at 16:29
