ABSTRACT
This chapter shows that how two kinds of multivariate analysis: may be used to detect patterns of morphological variation. They are factor analysis, and multiple discriminant or canonical analysis. The chapter describes whether specific patterns of cranial variation found among individuals of a population—which may assume to be variation primarily of genetic origin. General cranial expansion associated with occipital generosity is even expressed by low loadings for total length, length of frontal bone, and bistephanic breadth. Factor analysis may be expected to produce factors based on double-tons, or pairs of correlated variables having "spurious" correlation not strongly correlated with other variables. A discriminant analysis, by resolution of a different matrix, will produce an eigenvector—here a discriminant function—a set of coefficients which is used to multiply an individual's measurements to give discriminant score for that function. The functions, although confirming some of the recognized distinctions of "classic" Neanderthals, may serve mainly to place them taxonomically outside the range of recent man.
