-===<math>p</math>  Ratio===

-In the Crow Extended - Continuous evaluation, there is a certain probability of  not incorporating a corrective action by time  <math>T</math> . This is the additional (third parameter), as compared to the Crow Extended model. We define  <math>p</math>  as:
-::<math>p=\frac{\text{All modes such that, if seen, will be corrected at time }T\text{, or later}}{\text{All failure modes such that, if seen, the corrective action will be delayed}}</math>
-It is assumed that the ratio  <math>p</math>  remains fixed over    . This implies that each time a distinct failure mode is seen, the probability that the corrective action is delayed until time  <math>T</math>  or later is  <math>p</math> . In other words, each time a new BD mode is seen over  <math>(0,T)</math>  there is a probability  <math>p</math>  that the corrective action for that mode will not have been incorporated into the system by time  <math>T</math> . Under the Crow Extended two-parameter model, this probability is always equal to 1 at time  <math>T.</math>
