ratio estimation
1Burning Cost Ratio — An insurance industry calculation of excess losses divided by total subject premium. The burning cost ratio is an experience based insurance rating method commonly used in determining rates for excess of loss reinsurance, or the insurance that… …
2Odds ratio — The odds ratio [1][2][3] is a measure of effect size, describing the strength of association or non independence between two binary data values. It is used as a descriptive statistic, and plays an important role in logistic regression. Unlike… …
3Inverse Mills ratio — In statistics, the inverse Mills ratio, named after John P. Mills, is the ratio of the probability density function to the cumulative distribution function of a distribution. Use of the inverse Mills ratio is often motivated by the following… …
4Minimum distance estimation — (MDE) is a statistical method for fitting a mathematical model to data, usually the empirical distribution. Contents 1 Definition 2 Statistics used in estimation 2.1 Chi square criterion …
5Maximum spacing estimation — The maximum spacing method tries to find a distribution function such that the spacings, D(i), are all approximately of the same length. This is done by maximizing their geometric mean. In statistics, maximum spacing estimation (MSE or MSP), or… …
6Maximum a posteriori estimation — In Bayesian statistics, a maximum a posteriori probability (MAP) estimate is a mode of the posterior distribution. The MAP can be used to obtain a point estimate of an unobserved quantity on the basis of empirical data. It is closely related to… …
7F-ratio — In oceanic biogeochemistry, the f ratio is the fraction of total primary production fuelled by nitrate (as opposed to that fuelled by other nitrogen compounds such as ammonium). This fraction is significant because it is assumed to be directly… …
8Monotone 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 …
9Sequential 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… …
10Standardized mortality ratio — The standardized mortality ratio or SMR in epidemiology is the ratio of observed deaths to expected deaths, where expected deaths are calculated for a typical area with the same age and gender mix by looking at the death rates for different ages… …
