WebFor oblique rotation, each column of target must contain at least m - 1 zeros. B = rotatefactors(A,'Method','promax') rotates A to maximize the promax criterion, equivalent to an oblique Procrustes rotation with a target created by an orthomax rotation. Use the four orthomax parameters to control the orthomax rotation used internally by promax. Factor rotation is a commonly employed step in EFA, used to aide interpretation of factor matrixes. For any solution with two or more factors there are an infinite number of orientations of the factors that will explain the data equally well. Because there is no unique solution, a researcher must select a single solution from the infinite possibilities. The goal of factor rotation is to rotate factors in multidimensional space to arrive at a solution with best simple structure. Th…

WebAug 1, 2016 · The varimax rotation is a type of orthogonal rotation, which means the rotated axes remain perpendicular (like the two-dimensional example we just described). Another class of rotations are oblique rotations, which means the rotated axes are not perpendicular. One example of an oblique rotation is “promax”. WebVarimax rotation is orthogonal rotation in which assumption is that there is no intercorrelations between components.
