Definición

variance

n. 1) an exception to a zoning ordinance, authorized by the appropriate governmental body such as a planning commission, zoning board, county commissioners or city council. Example: the zoning ordinance requires that no residences can be built within 10 feet of a property's back line, but due to the odd shape of May Matheson's property, she needs to build her dream house within five feet of the property line at one point. The local zoning board listens to her plea, finds that the neighbors do not object, and grants her a variance to build closer to the back line. 2) a difference between what the prosecution has charged and what it has proved against a criminal defendant. 3) a difference between what is alleged in a civil complaint and what is proved. A substantial variance may be fatal to the prosecution's case against the accused or fatal to a plaintiff's (the person who filed the suit) lawsuit. In each case the judge can dismiss the case as a matter of law, without sending the factual issues to the jury. In criminal cases the test of a fatal variance is somewhat stricter than in a civil lawsuit, since a minor difference between the charge and the proof may mislead the defendant and deny him/her "due process."

Law of total variance

In probability 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, states that if $X$ and $Y$ are random variables on the same probability space, and the variance of $Y$ is finite, then

In language perhaps better known to statisticians than to probability theorists, the two terms are the "unexplained" and the "explained" components of the variance respectively (cf. fraction of variance unexplained, explained variation). In actuarial science, specifically credibility theory, the first component is called the expected value of the process variance (EVPV) and the second is called the variance of the hypothetical means (VHM). These two components are also the source of the term "Eve's law", from the initials EV VE for "expectation of variance" and "variance of expectation".
