PATH ANALYSIS (2014 EDITION)

An illustrated tutorial and introduction to path analysis using SPSS, AMOS, SAS, or Stata. Suitable for introductory graduate-level study.

The 2014 edition is a major update to the 2012 edition. Among the new features are these:

• Over double the page length (74 pp. rather than 35)
• Over four times as many illustrative figures (45 rather than 11)
• Now covers SAS and Stata as well as SPSS and AMOS
• Covers both regression-based and SEM-based methods
• Totally rewritten and reformatted, with new FAQs added
