A set of methods where one outcome measure (e.g. health related quality of life weights) are statistically predicted from one or more other measures.

Markov Model

A type of quantitative modelling 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 remaining in the same state). Typically, states have a uniform time period, and transition probabilities remain constant over time.


Systematic methods that use statistical techniques for combining results from different studies to obtain a quantitative estimate of the overall effect of a particular intervention or variable on a defined outcome. This combination may produce a stronger conclusion than can be provided by any individual study.
