Correlation Coefficient

Business / Finance / Correlation Coefficient: Statistical measure of the degree to which the movements of two variables (stock/option/convertible prices or returns) are related. See: Correlation coefficient.

Fourier Ring Correlation (FRC)

Science / Spiders / Fourier Ring Correlation (FRC): a measure of statistical dependency between two averages, computed by comparison of rings in Fourier space [Saxton and Baumeister, 1982]. As the Differential Phase Residual, the FRC is used to establi MORE

Discharge Coefficient

Technology / Rockets / Discharge Coefficient: Downrating of the area of an orifice or nozzle due to flow separation or friction. MORE

Fourier Shell Correlation (FSC)

Science / Spiders / Fourier Shell Correlation (FSC): same as Fourier ring correlation, except that values of the discrete Fourier transforms are compared within corresponding shells, instead of rings [van Heel, 1987b. MORE

Information Coefficient (IC)

Business / Finance / Information Coefficient (IC): Condition that information is known to some, but not all, participants. MORE

Stoichiometric Coefficient

Science / Chemistry / Stoichiometric Coefficient: The coefficients given before substances in a balanced chemical equation. For example, the stoichiometric coefficient of carbon dioxide in the following reaction is 4: 2 C2H6(g) + 7 O2(g) rightarrow 4 MORE

Spatial Autocorrelation

Science / Marine Biology / Spatial Autocorrelation: A situation in which some parameter at any location (e.g., population density) can be predicted through a knowledge of the values of the parameter in other locations MORE
