hi can some one please explain  what the following means in the multi state error model ...
example given in the manual	
//----------------------------------

 # Durations for each of the states, tmp, tmp1 and tmp2, respectively
#       set m_periods [list .75 .25]
        # Transition state model matrix
#       set m_transmx { {0.9 0.1} 
#       {0.2 0.8 } }
#      
//--------------------------------
if m_periods is the time in each state ..
is m_transmx the probablities..... 
is the above way correct for a 2 state markov model ..
