Cumulative intensity function
The intensity of a counting process is a measure of the rate of change of its predictable part. If a stochastic process is a counting process, then it is a submartingale, and in particular its Doob-Meyer decomposition is where is a martingale and is a predictable increasing process. is called the cumulative intensity of and it is related to by WebThe value(s) of the cumulative hazard function at the specified x value(s).
