Crocker–Henderson odor system

a theory that posits four primary odor qualities: acid, burnt, caprylic, and fragrant. The presence of each primary in an odor is assessed via a 9-point scale (0–8) indicating the relative intensity of each quality. See also Henning’s odor prism. [Ernest C. Crocker (1888–1964) and Lloyd F. Henderson, U.S. chemists]

factor method

any means by which latent variables (factors) are extracted or identified in factor analysis. Widely used factor methods include principal components analysis, which seeks to find a set of linear combinations called components that help explain the correlations among variables; and principal-axis factor analysis, in which underlying dimensions or factors are sought to explain the correlations among variables after separating out communality and putting aside the error variance in a set of variables.
