* Regression analysis, a statistical technique for estimating the relationships among variables.

Regression testing is any type of software testing that seeks to uncover new software bugs, or regressions, in existing functional and non-functional areas of a system after changes, such as enhancements, patches or configuration changes, have been made to them.

Regression testing can be used to test a system efficiently by systematically selecting the appropriate minimum set of tests needed to adequately cover a particular change.

Regression testing is an integral part of the extreme programming software development method.

Regression testing can be used not only for testing the correctness of a program, but often also for tracking the quality of its output.

Regression tests can be broadly categorized as functional tests or unit tests.

* Regression – Attempts to find a function which models the data with the least error.

Regression is the situation in which a coastline moves in the direction of the sea.

Empirical models that attempt to estimate the public investment and economic growth link involve a wide variety including: the Cobb-Douglas production function ; a behavioral approach cost / profit function which includes public capital stock ; Vector Auto Regression ( VAR ) models ; and government investment growth regressions.

Regression towards the mean can be defined for any bivariate distribution with identical marginal distributions.

The concept of regression comes from genetics and was popularized by Sir Francis Galton during the late 19th century with the publication of Regression towards mediocrity in hereditary stature.

Regression toward the mean simply says that, following an extreme random event, the next random event is likely to be less extreme.

Regression analysis estimates what the average firm should be able to achieve.

Regression of CIS effectively results in the progressive conversion of a malignant neoplasm to a benign one, to a localized area of normal or near-normal tissue, with or without associated scar tissue, which often forms secondary to apoptosis, necrosis, and fibrosis.

Regression is most often manifested after exposure to prolonged changes in the quality and intensity of environmental and / or immunological stimuli.

Ordinary methods of diplomacy within the free world are inadequate, said the former Prime Minister.

Bridges, tunnels and ferries are the most common methods of river crossings.

Since conventional methods are insensitive at the low frequencies of these molecular transitions, the paramagnetic resonance method is being used instead.

These data are not of the precision obtainable by the methods previously mentioned, but the vast number of approximate values available will be useful in many areas.

Various methods of pulsing, scanning, and displaying these sound waves are used to detect submarines, map ocean floors, and even communicate under water.

Among the newest fabrication methods to enter the display field are expandable styrene molding and blow molding.

Such an instrument is expected to be especially useful if it could be used to measure the elasticity of heavy pastes such as printing inks, paints, adhesives, molten plastics, and bread dough, for the elasticity is related to those various properties termed `` length '', `` shortness '', `` spinnability '', etc., which are usually judged by subjective methods at present.

The statistical analyses of achievement in relation to anxiety and teaching methods and the interactions of the two are presented in Tables 3 and 4.

They are both trend-following methods.

The foregoing have been methods of charting prices, but now let us look at some of the other indices that are customarily charted, and which are looked to for their forecasting abilities.

The methods and results of this comparative analysis are described in Appendix Aj.

What is missing is work that would answer, presumably by the use of survey methods and Guttman-type attitude scales, such questions as these: What are the components of the feeling-state described as alienation??

Biological anthropologists are interested in both human variation and in the possibility of human universals ( behaviors, ideas or concepts shared by virtually all human cultures ) They use many different methods of study, but modern population genetics, participant observation and other techniques often take anthropologists " into the field ," which means traveling to a community in its own setting, to do something called " fieldwork.
