Parameter — Pa*ram e*ter, n. [Pref. para + meter: cf. F. param[ e]tre.] 1. A constant number which is part of a theory, function, or calculation, whose value is not determined by the form of the theory or equation itself, and may in some cases be arbitrary… … The Collaborative International Dictionary of English
Ratio distribution — A ratio distribution (or quotient distribution ) is a statistical distribution constructed as the distribution of the ratio of random variables having two other distributions.Given two stochastic variables X and Y , the distribution of the… … Wikipedia

Likelihood-ratio test — The likelihood ratio, often denoted by Lambda (the capital Greek letter lambda), is the ratio of the maximum probability of a result under two different hypotheses. A likelihood ratio test is a statistical test for making a decision between two… … Wikipedia

Sequential probability ratio test — The sequential probability ratio test (SPRT) is a specific sequential hypothesis test, developed by Abraham Wald. [cite journal first=Abraham last=Wald title=Sequential Tests of Statistical Hypotheses journal=Annals of Mathematical Statistics… … Wikipedia
Monotone likelihood ratio — A monotonic likelihood ratio in distributions f(x) and g(x) The ratio of the density functions above is increasing in the parameter x, so f(x)/g(x) satisfies the monotone likelihood ratio property. In statistics, the monoto … Wikipedia
Thrust-to-weight ratio — is, as its name suggests, the ratio of instantaneous thrust to weight (where weight means weight at the Earth’s surfaceSutton (7th edition pg 442) thrust to weight ratio F/Wg is a dimensionless parameter that is identical to the acceleration of… … Wikipedia
Hazard ratio — The hazard ratio in survival analysis is the effect of an explanatory variable on the hazard or risk of an event. For a less technical definition than is provided here, consider hazard ratio to be an estimate of relative risk and see the… … Wikipedia
Monotone likelihood ratio property — is a property of a family of probability distributions described by their probability density functions (PDFs). A family of density functions { f heta (x)} { hetain Theta} indexed by a parameter heta taking values in a set Theta is said to have… … Wikipedia
Positivity/negativity ratio — Positivity and negativity are powerful feedback processes in human behavior. Positive feedback encourages us to continue doing what we have done so far. Negative feedback, on the contrary, generally acts as a warning signal that tells us to… … Wikipedia
