A statistical model for sequences in which the probability of each letter depends on the letters that precede it.

a finite-state device (also called a word chain device) that, when faced with a choice between two or more lists, chooses among them according to specified probabilities

a finite state machine which changes state once every time unit and each time t that a state j is entered, a speech vector is generated from the probability density

a state-transition model in which persons entering the model cycle within and between different health states according to specified probabilities

a way to represent a changing set of health states over time, where there is a known probability or rate of transition from one health state to another

A type of quantitative modeling that involves a specified set of mutually exclusive and exhaustive states (e.g., of a given health status), and for which there are transition probabilities of moving from one state to another (including of remaining in the same state). Typically, states have a uniform time period, and transition probabilities remain constant over time.

A decision-analytic model that characterizes the prognosis of a cohort of patients by assigning them to a fixed number of health states and modeling transitions among those states.

Probability that the user of each brand in a category will switch next time to each other brand.
