data correlation
1Correlation and dependence — This article is about correlation and dependence in statistical data. For other uses, see correlation (disambiguation). In statistics, dependence refers to any statistical relationship between two random variables or two sets of data. Correlation …
2Correlation clustering — In machine learning, correlation clustering or cluster editing operates in a scenario where the relationship between the objects are known instead of the actual representation of the objects. For example, given a signed graph G = (V,E) where the… …
3Data collection — is a term used to describe a process of preparing and collecting data, for example, as part of a process improvement or similar project. The purpose of data collection is to obtain information to keep on record, to make decisions about important… …
4Correlation does not imply causation — (related to ignoring a common cause and questionable cause) is a phrase used in science and statistics to emphasize that correlation between two variables does not automatically imply that one causes the other (though correlation is necessary for …
5Correlation coefficient — may refer to: Pearson product moment correlation coefficient, also known as r, R, or Pearson s r, a measure of the strength of the linear relationship between two variables that is defined in terms of the (sample) covariance of the variables… …
6Data dredging — (data fishing, data snooping) is the inappropriate (sometimes deliberately so) use of data mining to uncover misleading relationships in data. Data snooping bias is a form of statistical bias that arises from this misuse of statistics. Any… …
7Correlation spectroscopy — is one of several types of two dimensional nuclear magnetic resonance (NMR) spectroscopy. Other types of two dimensional NMR include J spectroscopy, exchange spectroscopy (EXSY), and Nuclear Overhauser effect spectroscopy (NOESY). Two dimensional …
8Correlation (disambiguation) — Correlation is a measure of relationship between two mathematical variables or measured data values, which includes the Pearson correlation coefficient as a special case. Correlation may also refer to: Electronic correlation, a description of the …
9Data loss — is an error condition in information systems in which information is destroyed by failures or neglect in storage, transmission, or processing. Information systems implement backup and disaster recovery equipment and processes to prevent data loss …
10Data center infrastructure management — (DCIM) is the integration of information technology (IT) and facility management disciplines to centralize monitoring, management and intelligent capacity planning of a data center s critical systems. Achieved through the implementation of… …
