Table of Cos ψ ij , Scalar Products Derived Using Ekman's Formula 5
Le Roy A. Stone, Gary J. Coles · Perceptual and Motor Skills · 1970
A table of cos ψ ij s was computed from 100 s ij values ranging from 0.01 to 1.00 using the equation developed by Ekman for this purpose. These derived cos ψ ij s may be treated as the scalar products in Ekman's revised method of similarity analysis.
