product-moment correlation coefficient
11Corrélation de spearman — En statistique, la corrélation de Spearman (nommée d après Charles Spearman) est étudiée lorsque deux variables statistiques semblent corrélées sans que la relation entre les deux variables soit de type affine. Elle consiste à trouver un… …
12Pearson correlation coefficient — the most common correlation coefficient; it is the covariance of two random variables divided by the product of their standard deviations. Called also product moment correlation c. See also correlation c …
13Correlation 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 …
14Correlation — In probability theory and statistics, correlation, (often measured as a correlation coefficient), indicates the strength and direction of a linear relationship between two random variables. In general statistical usage, correlation or co relation …
15Coefficient of determination — In statistics, the coefficient of determination R2 is used in the context of statistical models whose main purpose is the prediction of future outcomes on the basis of other related information. It is the proportion of variability in a data set… …
16coefficient of correlation — noun a statistic representing how closely two variables co vary; it can vary from 1 (perfect negative correlation) through 0 (no correlation) to +1 (perfect positive correlation) what is the correlation between those two variables? • Syn:… …
17Corrélation de Spearman — En statistique, la corrélation de Spearman (nommée d après Charles Spearman) est étudiée lorsque deux variables statistiques semblent corrélées sans que la relation entre les deux variables soit de type affine. Elle consiste à trouver un… …
18Correlation function — For other uses, see Correlation function (disambiguation). A correlation function is the correlation between random variables at two different points in space or time, usually as a function of the spatial or temporal distance between the points.… …
19Coefficient of variation — In probability theory and statistics, the coefficient of variation (CV) is a normalized measure of dispersion of a probability distribution. It is also known as unitized risk or the variation coefficient. The absolute value of the CV is sometimes …
