Definition: Passemeasures, also known as pass measures or passivity measures, are a type of statistical test used to determine whether an event is likely to occur within a given time horizon. The goal of this measure is to compare the expected frequency of an event over a long period of time against its observed frequency in a short period. In simpler terms, a passemeasure involves comparing the probability that an event will occur in a certain time interval with the probability it actually does occur. This can be useful
