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:

S1 S2 S3 SA 0 S1 0 S2 0.3 0.4 0.3 S3 0.5 0.3 0.2 0 SA 0
