• Note that the rotation matrix is defined for “factor score” matrix ξ, not for the loading matrix Λ--- makes no difference in the orthogonal case, but should be clear in the “oblique” case • Rotational indeterminacy shown in the covariance structure:

object of the rotation is to try to ensure that all variables have high loadings only on one factor. There are two types of rotation method, orthogonal and oblique rotation. In orthogo-nal rotation the rotated factors will remain uncorrelated whereas in oblique rotation the resulting factors will be correlated.

Exploratory Factor Analysis 2 2.1. Factor analysis in a nutshell The starting point of factor analysis is a correlation matrix, in which the intercorrelations between the studied variables are presented. The dimensionality of this matrix can be reduced by “looking for variables that correlate highly with a group of other variables, but correlate

Factor Rotation: Orthogonal vs. Oblique Rotation ! Oblique: Factors are NOT independent. Change in “angle.” ! oblimin: minimize covariance of squared loadings between factors. ! promax: simplify orthogonal rotation by making small loadings even closer to zero. !

principal component analysis (pca) framework. Pca starts with a data matrix denoted Y with I rows and J columns, where each row represents a unit (in gen-eral subjects) described by J measurements which are almost always expressed as Z-scores. The data matrix is then decomposed into scores (for the subjects)

Factor loadings should be reported to two decimal places and use descriptive labels in addition to item numbers. Correlations between the factors should also be included, either at the bottom of this table, in a separate table, or in an appendix. The correlation matrix should be included so that others people can re-conduct a factor analysis.
