Options:

• flag: output to flag factor loading with absolute values greater than the specified size. eg flag = .40
• method: extracting method

• prin: principal factors for a principal component analysis
• mineigen: critical eigenvalue to retain and rotate any component whose eigenvalue is specified or lager.
• nfact: number of components to be retained and rotated
