Variance
12 linksIn probability theory and statistics, variance is the expectation of the squared deviation of a random variable from its population mean or sample mean.
Ronald Fisher
10 linksSir Ronald Aylmer Fisher (17 February 1890 – 29 July 1962) was a British polymath who was active as a mathematician, statistician, biologist, geneticist, and academic.
Probability distribution
9 linksIn probability theory and statistics, a probability distribution is the mathematical function that gives the probabilities of occurrence of different possible outcomes for an experiment.
Standard deviation
8 linksIn statistics, the standard deviation is a measure of the amount of variation or dispersion of a set of values.
Linear regression
11 linksIn statistics, linear regression is a linear approach for modelling the relationship between a scalar response and one or more explanatory variables (also known as dependent and independent variables).
Estimator
8 linksIn statistics, an estimator is a rule for calculating an estimate of a given quantity based on observed data: thus the rule (the estimator), the quantity of interest (the estimand) and its result (the estimate) are distinguished.
Mathematics
5 linksArea of knowledge that includes such topics as numbers , formulas and related structures (algebra), shapes and the spaces in which they are contained (geometry), and quantities and their changes (calculus and analysis).

Some areas of mathematics, such as statistics and game theory, are developed in close correlation with their applications and are often grouped under applied mathematics.
Mean squared error
7 linksIn statistics, the mean squared error (MSE) or mean squared deviation (MSD) of an estimator (of a procedure for estimating an unobserved quantity) measures the average of the squares of the errors—that is, the average squared difference between the estimated values and the actual value.
Statistical dispersion
4 linksIn statistics, dispersion (also called variability, scatter, or spread) is the extent to which a distribution is stretched or squeezed.
Bias of an estimator
6 linksIn statistics, the bias of an estimator (or bias function) is the difference between this estimator's expected value and the true value of the parameter being estimated.
