 Both time-independent cSTM where transition probabilities are constant over time  and time-dependent cSTM where transition probabilities vary over time are represented. For the time-dependent cSTM, we consider transition probabilities dependent on age and state residence .
<meaning-changed>  Both time-independent cSTM where transition probabilities are constant over time  and time-dependent cSTM where transition probabilities vary over time are represented. For the time-dependent cSTM, we consider transition probabilities dependent on age and state residence .
 Both time-independent cSTM where transition probabilities are constant over time and time-dependent cSTM where transition probabilities vary by age and are dependent on time spent in a health state (state residence) .
