First hitting time distribution

In many real world applications, a first-hitting-time (FHT) model has three underlying components: (1) a parent stochastic process $${\displaystyle \{X(t)\}\,\,}$$, which might be latent, (2) a threshold (or the barrier) and (3) a time scale. The first hitting time is defined as the time when the stochastic process first … See more Events are often triggered when a stochastic or random process first encounters a threshold. The threshold can be a barrier, boundary or specified state of a system. The amount of time required for a See more First hitting times are central features of many families of stochastic processes, including Poisson processes, Wiener processes, gamma processes, and Markov chains, … See more The time scale of the stochastic process may be calendar or clock time or some more operational measure of time progression, such … See more A common example of a first-hitting-time model is a ruin problem, such as Gambler's ruin.
