The basic first hitting time model. A general mathematical formulation of a first hitting time model considers a stochastic process in time, {X (t), t⩾0} and an absorbing setH in the state space of the process. The first hitting time is the random variable S defined as follows: (1) S= inf t: X (t)∈H. In other words, the first hitting ...
