It was developed by Louis Leon Thurstone in 1928, originally as a means of measuring attitudes towards religion.
For the basic Case V, the frequency dominance matrix is translated into proportions and interfaced with the standard scores.
The scale is then obtained as a left-adjusted column marginal average of this standard score matrix (Thurstone, 1927b).
The inability of the pair comparisons algorithm to handle these cases imposes considerable limits on the applicability of the method.
The Rasch model has a close conceptual relationship to Thurstone's law of comparative judgment (Andrich, 1978), the principal difference being that it directly incorporates a person parameter.
