What is orthogonal rotation?
a transformational system used in factor analysis in which the different underlying or latent variables are required to remain separated from or uncorrelated with one another.
What is oblique rotation?
a transformational system used in factor analysis when two or more factors (i.e., latent variables) are correlated. Oblique rotation reorients the factors so that they fall closer to clusters of vectors representing manifest variables, thereby simplifying the mathematical description of the manifest variables.
Is Oblimin rotation oblique?
As an oblique rotation method, Oblimin permits correlations among the constructed sets, and in case of uncorrelated data, rotations produce similar results as orthogonal rotation. …
What is the difference between orthogonal rotation and oblique rotation?
The major difference between orthogonal and oblique rotation is that the orthogonal rotation preserves the orthogonality of the factors (i.e., the correlations between them remain equal to zero), whereas the oblique rotation allows the new factors to be correlated.
What is orthogonal rotation in factor analysis?
Orthogonal rotations constrain the factors to be uncorrelated. Although often favored, in many cases it is unrealistic to expect the factors to be uncorrelated, and forcing them to be uncorrelated makes it less likely that the rotation produces a solution with a simple structure.
What do oblique and orthogonal refer to?
Orthogonal and oblique are two different types of rotation methods used to analyze information from a factor analysis. Rotations where factors are not correlated are orthogonal. So rotation methods that are correlated are oblique while rotation of uncorrelated factors is orthogonal.
What are the purpose and the characteristics of a Oblimin rotation?
Oblimin is a classic example of orthogonal rotation. The goal of an oblimin rotation is to obtain simple structure while allowing the factors to be correlated with each other. The magnitude of the correlation between the factors can be set by the researcher.
What is a Quartimax rotation?
Quartimax rotation is a form of orthogonal rotation used to transform vectors associated with principal component analysis or factor analysis to simple structure.
Is varimax rotation orthogonal or oblique?
Varimax, along with quartimax, are two of the most common types of orthogonal rotations (Merenda, 1997).
