Additive Structure in Qualitative Data: An Alternating Least Squares Method with Optimal Scaling Features
And Others; de Leeuw, Jan
Psychometrika, 41, 4, 471-503, Dec 76
An alternating least squares procedure is proposed to investigate the additive structure of qualitative data. The method also permits experimental variables to be measured at the ordinal level. The method is shown to be convergent and includes several previously proposed methods as special cases. Examples are provided. (Author/JKS)
