71Determining the number of clusters in a data set — Determining the number of clusters in a data set, a quantity often labeled k as in the k means algorithm, is a frequent problem in data clustering, and is a distinct issue from the process of actually solving the clustering problem. For a certain …
72Analysis of variance — In statistics, analysis of variance (ANOVA) is a collection of statistical models, and their associated procedures, in which the observed variance in a particular variable is partitioned into components attributable to different sources of… …
73Markowitz Efficient Set — A set of portfolios with returns that are maximized for a given level of risk based on mean variance portfolio construction. The efficient solution set to a given set of mean variance parameters (a given riskless asset and a given risky basket of …
74Pooled variance — In statistics, many times, data are collected for a dependent variable, y, over a range of values for the independent variable, x. For example, the observation of fuel consumption might be studied as a function of engine speed while the engine… …
75Minimum-variance unbiased estimator — In statistics a uniformly minimum variance unbiased estimator or minimum variance unbiased estimator (UMVUE or MVUE) is an unbiased estimator that has lower variance than any other unbiased estimator for all possible values of the parameter. The… …
76Efficiency Variance — The difference between the theoretical amount of inputs required to produce a unit of output and the actual amount of inputs used. In manufacturing, efficiency variance can be used to analyze the effectiveness with respect to labor, materials,… …
77revision variance — planning variance In standard costing, a variance that is expected to arise from the difference between a standard as originally set and the standard as modified to reflect changed circumstances (the current standard). An operational variance can …
78analysis of variance — Statistics. a procedure for resolving the total variance of a set of variates into component variances that are associated with defined factors affecting the variates. Also called variance analysis. [1935 40] * * * …
79analysis of variance — noun a statistical method for making simultaneous comparisons between two or more means; a statistical method that yields values that can be tested to determine whether a significant relation exists between variables • Syn: ↑ANOVA • Topics:… …
80Analysis Of Variance - ANOVA — A statistical analysis tool that separates the total variability found within a data set into two components: random and systematic factors. The random factors do not have any statistical influence on the given data set, while the systematic… …
