**IDIOSCAL**Carroll & Chang (1972). As T2, but the two reduced modes are equal, and thus the extended core matrix is symmetric in its frontal planes. Allows for both ideosyncratic rotations of axes in the common stimulus space, and individually different weighting of these axes. Component matrices are not necessarily orthogonal.

**INDSCAL**Carroll & Chang (1970). As IDIOSCAL, but with the additional restriction that the frontal planes are diagonal, i.e. no idiosyncratic rotations are allowed. The model can also be interpreted to have three reduced modes of equal numbers of components, and a three-mode identity matrix.
