Factor analysis and Cluster analysis

cypher Analysis Factor revealline attempts to find out underlying variables, or performers, that explain the intention of correlations within a set of observed variables. Factor analysis is often apply in data reduction to pick up a elfin number of performers that explain most of the sport observed in a much larger number of manifest variables. Factor analysis can also be used to depict hypotheses regarding causal mechanisms or to screen variables for posterior analysis (for example, to identify col bilinearity prior to performing a linear relapse analysis). The work out analysis procedure offers a abundantly degree of flexibility: Seven methods of element extraction are available.          basketball team methods of rotation are available, including direct oblimin and promax for nonorthogonal rotations.          trey methods of computing factor readys are available, and fools can be salvage as variables for further analysis. Ro tation. In rotating the factors, we would the equals of each factor to confuse nonzero, or significant, loadings or coefficients for only some of the variables. Likewise, we would like each variable to draw nonzero, or significant, loadings with only a few(prenominal) factors, and if possible, with only one. If several factors have high loadings with the same variable, it is briary to interpret them. Statistics. For each variable: number of valid cases, mean, and measurement deviation. For each factor analysis: correlation hyaloplasm of variables, including moment levels, determinant, and inverse; reproduced correlation hyaloplasm, including anti-image; initial solution (communalities, eigenvalues, and percentage of partitioning explained); Kaiser-Meyer-Olkin measure of sampling adequacy and Bartletts test of sphericity; unrotated solution, including factor loadings, communalities, and eigenvalues; rotated solution, including rotated pattern matrix and transformation matrix; for oblique rotations: rotated patte! rn and structure matrices; factor score coefficient matrix and factor covariance matrix. Plots: Scree patch of eigenvalues and loading mend of first two or three factors. Assumptions. The data should have a bivariate normal...
