If your goal is to simply reduce your variable list down into a linear combination of smaller … See more Without rotation, the first factor is the most general factor onto which most items load and explains the largest amount of variance. This may … See more We know that the goal of factor rotation is to rotate the factor matrix so that it can approach simple structure in order to improve … See more As a special note, did we really achieve simple structure? Although rotation helps us achieve simple structure, if the interrelationships do not hold itself up to simple structure, we … See more In oblique rotation, the factors are no longer orthogonal to each other (x and y axes are not 90∘angles to each other). Like orthogonal rotation, the goal is rotation of the … See more WebResults indicate that the RS data fit a 5-factor model reasonably well. A subsequent bifactor analysis identified a considerable proportion of common variance across factors, suggesting the presence of a strong general ED factor, two distinct group factors (Inability to Learn and Inappropriate Behavior), and three weak group factors.
