Rotated Solution. A rotation method must be selected to obtain a rotated solution.
For orthogo
nal rotations, the rotated pattern matrix and factor transformation
matrix are displayed. For oblique rotations, the pattern, structure, and factor
correlation matrices are displayed.
 Factor Loading Plot. Three-dimensional factor loading plot of the first three
factors. Fo
r a two-factor solution, a two-dimensional plot is shown. The plot is
not displayed if only one factor is extracted. Plots display rotated solutions if
rotation is requested.
Maximum Iterations for Convergence. Allows you to specify the maximum number of
steps the a
lgorithm can take to perform the rotation.
Factor Analysis Scores
Figure 29-7
Factor Analysis Factor Scores dialog box
Save as variables. Creates one new variable for each factor in the final solution. Select
one of the following alternative methods for calculating the factor scores: regression,
Bartle
tt, or Anderson-Rubin.
 Regres
sion M ethod.
A method for estimating factor score coefficients. The scores
produced have mean of 0 and a variance equal to the squared multiple correlation
between the estimated factor scores and the true factor values. The scores may be
correl
ated even when factors are orthogonal.
