In probability theory and statistics, variance is the expected value of the squared deviation from the mean of a random variable. The standard deviation...

In statistics and machine learning, the bias–variance tradeoff describes the relationship between a model's complexity, the accuracy of its predictions...

In statistics, pooled variance (also known as combined variance, composite variance, or overall variance, and written σ 2 {\displaystyle \sigma ^{2}} )...

Analysis of variance (ANOVA) is a collection of statistical models and their associated estimation procedures (such as the "variation" among and between...

The Allan variance (AVAR), also known as two-sample variance, is a measure of frequency stability in clocks, oscillators and amplifiers. It is named after...

in general, a variance is the difference between a budgeted, planned, or standard cost and the actual amount incurred/sold. Variances can be computed...

Variance is an online music and entertainment magazine, co-founded by Jonathan Robles in 2010 and based in Tulsa, Oklahoma. It also publishes a print magazine...

minimum-variance unbiased estimator (MVUE) or uniformly minimum-variance unbiased estimator (UMVUE) is an unbiased estimator that has lower variance than...

In applied statistics, a variance-stabilizing transformation is a data transformation that is specifically chosen either to simplify considerations in...

theory, the law of total variance or variance decomposition formula or conditional variance formulas or law of iterated variances also known as Eve's law...

The variance-gamma distribution, generalized Laplace distribution or Bessel function distribution is a continuous probability distribution that is defined...

stochastic processes, a part of the mathematical theory of probability, the variance gamma (VG) process, also known as Laplace motion, is a Lévy process determined...

manner in which variances are employed can differ greatly depending on the municipality. A variance may also be known as a standards variance, referring to...

Variance Films is a privately held film distribution company founded in 2008 that uses an innovative model of self-distribution combined with select elements...

In statistics, inverse-variance weighting is a method of aggregating two or more random variables to minimize the variance of the weighted average. Each...

statistics, the variance function is a smooth function that depicts the variance of a random quantity as a function of its mean. The variance function is...

A conditional variance swap is a type of variance swap or swap derivative product that allows investors to take exposure to volatility in the price of...

Algorithms for calculating variance play a major role in computational statistics. A key difficulty in the design of good algorithms for this problem is...

Price variance (Vmp) is a term used in cost accounting which denotes the difference between the expected cost of an item (standard cost) and the actual...

applications of multivariate time series analysis, a variance decomposition or forecast error variance decomposition (FEVD) is used to aid in the interpretation...
