The bootstrap method can be applied to multivariate component or factor analysis. This study details a strategy for using the bootstrap method in SPSS for robust statistical analysis.

Area of Science:

  • Statistics
  • Multivariate Analysis
  • Computational Statistics

Background:

  • The bootstrap method is a resampling technique for estimating sampling distributions.
  • Its application to multivariate component or factor analysis requires aligning resampled results in a common factor space.
  • Existing methods may lack clear implementation strategies for this complex analysis.

Purpose of the Study:

  • To present a practical strategy for applying the bootstrap method to multivariate component and factor analysis.
  • To provide program syntax for implementing this strategy in SPSS.
  • To demonstrate the utility of the proposed method using a real-world dataset.

Main Methods:

  • The study outlines a specific procedure for conducting bootstrap component/factor analysis.

  • It involves resampling data and aligning results within a common factor space.
  • SPSS syntax is provided for practical implementation.

    • Main Results:

    • The proposed strategy enables the empirical estimation of sampling distributions for component and factor analysis parameters.
    • The application to the Holzinger-Swineford data set illustrates the method's feasibility.
    • Summary statistics can be computed for each estimated parameter after alignment.

    Conclusions:

    • The bootstrap method offers a viable approach for robust multivariate component and factor analysis.
    • The provided SPSS syntax facilitates the application of this statistical technique.
    • This strategy enhances the reliability of inferential and descriptive statistics in factor analysis.
