In statistics, the Kolmogorov – Smirnov test ( K – S test ) is a nonparametric test for the equality of continuous, one-dimensional probability distributions that can be used to compare a sample with a reference probability distribution ( one-sample K – S test ), or to compare two samples ( two-sample K – S test ).

Kuiper's test is used in statistics to test that whether a given distribution, or family of distributions, is contradicted by evidence from a sample of data.

As with the K-S test, the discrepancy statistics D < sup >+</ sup > and D < sup >−</ sup > represent the absolute sizes of the most positive and most negative differences between the two cumulative distribution functions that are being compared.

This inability to distinguish distributions with a comb-like shape from continuous distributions is a key problem with all statistics based on a variant of the K-S test.

Fighting Fantasy books typically feature a system whereby the protagonist is randomly assigned scores in three statistics ( named Skill, Stamina, and Luck ) which, in conjunction with the player rolling a six-sided die, are used to resolve combats and test the protagonist's success in certain situations.

It is sometimes a difficult task to identify which part of the system represents this critical path, and some test tools include ( or can have add-ons that provide ) instrumentation that runs on the server ( agents ) and report transaction times, database access times, network overhead, and other server monitors, which can be analyzed together with the raw performance statistics.

Log-transformation of data before the application of parametric test, or the use of non-parametric statistics is recommended by several authors.

In statistics, a likelihood ratio test is a statistical test used to compare the fit of two models, one of which ( the null model ) is a special case of the other ( the alternative model ).

In statistics, the term chi-squared or has various uses, including the chi-squared distribution, the chi-squared test, and chi-squared target models.

They derived the CHSH inequality, which, as with John Bell's original inequality ( Bell, 1964 ), is a constraint on the statistics of " coincidences " in a Bell test experiment which is necessarily true if there exist underlying local hidden variables ( local realism ).

When the German distributor of the program took legal action to forbid publishing this rating, c't followed up with an exhaustive test showing that the program had virtually no effect other than giving false information about system statistics.

From these hypotheses predictions about specific events are derived ( e. g., " People who study a word list while listening to vocal music will remember fewer words on a later memory test than people who study a word list in silence .").

Einstein first derived this result by using an approximate metric representing the Newtonian limit and treating the orbiting body as a test particle.

Common examples of in vitro experiments include ( a ) cells derived from multicellular organisms ( cell culture or tissue culture ), ( b ) subcellular components ( e. g. mitochondria or ribosomes ), ( c ) Cellular or subcellular extracts ( e. g. wheat germ or reticulocyte extracts ), or ( d ) purified molecules in the test tube ( often proteins, DNA, or RNA, either individually or in combination ).

Scores derived by classical test theory do not have this characteristic, and assessment of actual ability ( rather than ability relative to other test-takers ) must be assessed by comparing scores to those of a " norm group " randomly selected from the population.

In fact, all measures derived from classical test theory are dependent on the sample tested, while, in principle, those derived from item response theory are not.

Countering Gould, Davis further explained that Goddard proposed that the low IQs of the sub-normally intelligent men and women who took the cognitive-ability test likely derived from their social environments rather than from their respective genetic inheritances, and concluded that " we may be confident that their children will be of average intelligence, and, if rightly brought up, will be good citizens.

Affinity laws are derived by requiring similitude between the test model and the application.

* In cladistics, congruence is a test of homology, or shared, derived character states, in which the distributions of supposed homologies among taxa are compared for consistency.

It derived much of its justification from two observations: first, that animals with hippocampal damage tend to be hyperactive ; second, that animals with hippocampal damage often have difficulty learning to inhibit responses that they have previously been taught, especially if the response requires remaining quiet as in a passive avoidance test.

Early analog synthesizers used technology derived from electronic analog computers and laboratory test equipment.

To test the inequality just derived, GHSZ need to make one more assumption, the " fair sampling " assumption.

TRIPs Article 30, covering limitations and exemptions to patent law, is also derived from a somewhat different three-step test, that includes " taking account of the legitimate interests of third parties.

The terms actus reus and mens rea developed in English Law are derived from the principle stated by Edward Coke, namely, actus non facit reum nisi mens sit rea, which means: " an act does not make a person guilty unless ( their ) mind is also guilty "; hence, the general test of guilt is one that requires proof of fault, culpability or blameworthiness both in behaviour and mind.

In order to test one's understanding it is necessary to present a question that forces the individual to demonstrate the possession of a model, derived from observable examples of that model's production or potential production ( in the case that such a model did not exist beforehand ).

Thought not a case involving charges under the Act, Brandenburg v. Ohio ( 1969 ) changed the " clear and present danger " test derived from Schenck to the " imminent lawless action " test, a considerably stricter test of the inflammatory nature of speech.

A Pearson's chi-squared test is then used to determine whether the observed frequencies in each group differ from expected frequencies derived from a distribution combining the two groups.

Unlike the symbolic interactionist framework, the many theories derived from symbolic interactionism, such as role theory and the versions of Identity Theory developed by Stryker, and Burke and colleagues, clearly define concepts and the relationships between them in a given context, thus allowing for the opportunity to develop and test hypotheses.

CCP derived from Failure mode and effects analysis ( FMEA ) from NASA via the munitions industry to test weapon and engineering system reliability.

Common-practice harmony is almost always derived from diatonic scales and tends to follow particular chord progressions that have withstood the test of time.

* Gramian matrix, used in mathematics to test for linear independence of functions

It originated from the TTF ( TESLA Test Facility ), which was built in 1997 to test the technology that was to be used in the planned linear collider TESLA, a project which was replaced by the ILC ( International Linear Collider ).

The best-known measure of metamerism is the Color Rendering Index ( CRI ), which is a linear function of the mean Euclidean distance between the test and reference spectral reflectance vectors in the CIE 1964 color space.

For example, a very common model is the straight line model which is used to test if there is a linear relationship between dependent and independent variable.

In the theory of generalized functions, certain kinds of generalized functions called distributions can be realized as linear functionals on spaces of test functions.

Adjustable linear power supplies are common laboratory and service shop test equipment, allowing the output voltage to be adjusted over a range.

The procedure bypasses the limitations produced by the linear dependencies inherent in test data.

It is possible to test whether a graph is bipartite, and to return either a two-coloring ( if it is bipartite ) or an odd cycle ( if it is not ) in linear time, using depth-first search.

* Pearson's chi-squared test, an alternative quality of fit statistic for generalized linear models.

For instance, linear algebra duality corresponds in this way to bilinear maps from pairs of vector spaces to scalars, the duality between distributions and the associated test functions corresponds to the pairing in which one integrates a distribution against a test function, and Poincaré duality corresponds similarly to intersection number, viewed as a pairing between submanifolds of a given manifold.

It was used mostly to solve what are now called affine linear problems by using a pair of test inputs and the corresponding pair of outputs.

For time-invariant linear systems in the state space representation, a convenient test to check if a system is observable exists.

The rationale for this test is that if rows are linearly independent, then each of the states is viewable through linear combinations of the output variables.

Once performed, it allows a linear time computation of the order of a finite group, group membership test ( is a given permutation contained in a group?

This is sufficient to ensure elementary equivalence, because the theory of unbounded dense linear orderings is complete, as can be shown by Vaught's test.
