regression coefficient

in a regression analysis, the weight associated with a unit change in a specific independent (predictor) variable on the dependent (outcome) variable, given the relationship of that predictor to other independent variables already in the model. This value may be standardized (see standardization) with a variance equal to 1 (in which case, it is called a beta coefficient), or it may be unstandardized and expressed in the units of the outcome variable being measured (in which case, it is called a B coefficient). Also called regression weight.

behavior coding

a method of recording observations in which defined labels are used by specially trained individuals to denote specific qualities and characteristics of behaviors as they are witnessed. For example, a developmental researcher might use the following coding scheme for infant vocalizations: (a) vowels; (b) syllables (i.e., consonant–vowel transitions); (c) babbling (a sequence of repeated syllables); and (d) other (e.g., crying, laughing, vegetative sounds such as cooing). Behavior coding systems typically are specific to a given study and the behaviors under investigation.
