Imagine this. What exactly were you planning on doing with that?. Let’s say you have a massive pile of data …. . You Could:. STA431: Spring 2013. See last slide for copyright information. THE TRUTH. (Well, closer to the truth, anyway). Why should the variance of the factors equal one?. Inherited from exploratory factor analysis, which was mostly a disaster.. Hans Baumgartner. Penn State University. x. 1. x. 2. x. 3. x. 4. x. 5. x. 6. x. 7. x. 8. What’s the structure underlying . 28 distinct . covariances. between . 8 observed variables?. The exploratory factor model. The purpose of factor analysis is to discover patterns in the relationships among the . variables. Factor Analysis. Form of multiple correlations. Checking for construct validity. Do questions measure the same dimension?. STA431: Spring 2013. See last slide for copyright information. THE TRUTH. (Well, closer to the truth, anyway). Regression-like models are close enough to the truth. Latent variables have unknown expected values and variances.. Strengthening the link between entrepreneurial proclivities and entrepreneurial outcomes. John Pisapia. Florida Atlantic University, USA. Keith Feit. Florida Atlantic University. John Morris. Florida Atlantic University. The basic objective of Factor Analysis is data reduction or structure detection.. The purpose of . data reduction. is to remove redundant (highly correlated) variables from the data file, perhaps replacing the entire data file with a smaller number of uncorrelated variables..
