"The so-called perfect scale, in the scalogram sense, is a
one-dimensional structure for data of the kind studied by item
analysis. The dimensionality of data is an empirical phenomenon,
and not to be determined by fiat. Therefore, I have suggested
abandoning the idea and terminology of scale construction in favor
of scale analysis."
Louis Guttman, Psychometrika, Vol. 36, No. 4, December, 1971.
Guttman analyzes data hoping to find a latent scale. Rasch constructs the latent scale from data intended to manifest that scale.
"Quality is never an accident. It is always the result of
intelligent effort. There must be the will to produce a superior
