11. Martingales with continuous time parameter can also be considered. 12. A more restricted class of processes are those with continuous time and discrete state space. 13. This is equivalent of sampling the response as above but using a continuous time expression. 14. We start by expressing this condition in continuous time : 15. A temporal point process is a stochastic time-series of binary events that occurs in continuous time . 16. If continuous time is assumed, the adjustment process is expressed as a differential equation such as 17. Lady Alice never married and held a continuous time of service for the next 24 years. 18. Discretization of continuous time systems using Zero-order hold ( ZOH ) and ADCs for digital controller implementation. 19. Continuous time makes use of differential equations.20. In brief, the evolution of a genetic sequence is modelled by a time-reversible continuous time Markov process.
