21Luminous coefficient — The luminous coefficient is a coefficient that measures the integrated fraction of the radiant power that contributes to its luminous properties as evaluated by means of the standard luminosity function. [cite book|title=Van Nostrand s Scientific …
22Absorption coefficient — The absorption coefficient α is a property of a material. It defines the extent to which a material absorbs energy, for example that of sound waves or electromagnetic radiation. Wallace Sabine was a pioneer of this concept in acoustics and… …
23Pearson product-moment correlation coefficient — In statistics, the Pearson product moment correlation coefficient (sometimes referred to as the MCV or PMCC, and typically denoted by r ) is a common measure of the correlation between two variables X and Y . In accordance with the usual… …
24Universal coefficient theorem — In mathematics, the universal coefficient theorem in algebraic topology establishes the relationship in homology theory between the integral homology of a topological space X, and its homology with coefficients in any abelian group A. It states… …
25Greatest common divisor of two polynomials — Informally, the greatest common divisor (GCD) of two polynomials p ( x ) and q ( x ) is the biggest polynomial that divides evenly into both p ( x ) and q ( x ). The definition is modeled on the concept of the greatest common divisor of two… …
26Earnings response coefficient — IntroductionThe earnings response coefficient, or ERC, is the estimated relationship between equity returns and the unexpected portion of (i.e., new information in) companies earnings announcements. In financial economics, arbitrage pricing… …
27Crop coefficient — Models of transpiration, or combined evapotranspiration (ET), from plants often combine an idealized or well calibrated reference crop response model with coefficients that account for differences in response observed for the crop of interest.… …
28Pearson 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 …
29beta coefficient — Stock market measure of price variability. A statistical measure of the relative risk of a common stock compared with the market for all stocks. ► “The conventional wisdom has been that portfolio betas are more stable than those for individual …
30Constitutive equation — Many defining equations are in the form of a constitutive equation, since parameters of a property or effect associated matter are characteristic to the substance in question. A large number of other defining equations not specifically… …
