In a sociological study of "conformity" by B. Cohen, the following Markov chain

model was used. There are four states: S1 = consistently nonconforming; S2

= indecisively nonconforming; S3 = indecisively conforming; S4 = consistently

conforming. In a group experiment subjects were found to switch states after

each session according to the following transition matrix:

S4 S1 S2 S3 O O S1 Oo .18 S2 06 .76 .27 .69 .04 S3 O S4
