Guttman1991: Guttman's Intelligence Facets

Description

The first dataset (Guttman1991) contains similarities and facets for Guttman's 3D cylindrical intelligence structure as published in Guttman (1991). The second dataset (Guttman1965) contains similarities and structural intelligence facets from Guttman (1965).

Usage

data(Guttman1991)
data(Guttman1965)

Format
