1.A number or symbol multiplied with a variable or an unknown quantity in an algebraic term, as 4 in the term 4x,orxin the termx(a+b). 2.A numerical measure of a physical or chemical property that is constant for a system under specified conditions, such as the coefficient of friction...
The meaning of COEFFICIENT is any of the factors of a product considered in relation to a specific factor; especially : a constant factor of a term as distinguished from a variable. How to use coefficient in a sentence.

chance-half correlation,split-half correlation- a correlation coefficient calculated between scores on two halves of a test; taken as an indication of the reliability of the test tetrachoric correlation,tetrachoric correlation coefficient- a correlation coefficient computed for two normally distributed variab...
Different from previous studies, the correlation coefficient calculated in this paper is a fuzzy number, rather than a crisp value. The idea is based on Zadeh's extension principle. A pair of nonlinear programs is formulated to find the α-cut of the fuzzy correlation coefficient. From ...
To account for that effect, the adjusted R2 (typically denoted with a bar over the R in R2) incorporates the same information as the usual R2 but then also penalizes for the number of predictor variables included in the model. As a result, R2 increases as new predictors are added to a ...
