gives the death rate. The higher the hazard of death, the more likely a currently living subject will die in the next short period of time. For behavioral observation, the hazard rate usually refers to repeatable, everyday behaviors, not so called trapping states like death. As such, it represents the likelihood of a subject performing the target behavior given that they are currently capable of doing so which at a minimum means they are not currently engaging in the behavior. You are not at risk of performing the behavior if you are currently performing the behavior. If we are recording behaviors because we are interested in models for hazard rates, we have to deal with the situation where the target behavior does not happen during the time we have available to observe. We call this simple right censoring (SRC). Models for hazard rates incorporate information about SRC to avoid biased estimates. SRC always happens unless we can observe subjects continually and forever. Other types of censoring commonly happen in MMSA as well, the most important being so called “competing risks censoring” (CRC). To understand CRC, suppose a parent can be in one of 3 states, negative (A), neutral (N), or positive (P) during an observation session. If the parent is currently neutral, N, then the parent is at risk for a state change to A or P. The state with the higher hazard rate will tend to happen first (say for example, P) and this event will censor the observation of a state change to A. P and A are competing and the winning state P has its winning time recorded along with the fact that it won and the losing state A has the same time recorded but along with the fact that it lost, i.e., was censored by P. CRC can be extensive in observation data and must be incorporated in MMSA to avoid biased estimates of hazard rates. Figure 1 shows a heuristic path diagram for a simple MMSA with 2 hazard rates, the initiation rate of child anger for session 1 and 2. These rates are predicted by concurrent child antisocial behavior (fall K child antisocial) and in turn predict change in future child antisocial behavior in the spring of grade 3. We will use the model in Figure 1 extensively to illustrate various applications of MMSA including models for estimating retest reliability of a single occasion (i.e., session) of observation and models for
