For an overview of Observation Oriented Modeling, please watch this ~15 minute video on Youtube. You’ll see the following types of advantages to the OOM approach:

  • Transparent Results
  • No Unrealistic Assumptions (e.g., normal population distributions, equal population variances, random sampling, etc.)
  • Meaningful “Effect Sizes”
  • Person-centered rather than statistics-centered
  • Accuracy is Primary
  • Patterns rather than Formulas

You can also get an overview of OOM from three of our recent papers:

  1. Observation Oriented Modeling: Preparing Students for Research in the 21st Century.
  2. Four Bad Habits of Modern Psychologists
  3. From Means and Variances to Persons and Patterns

The OOM book was published in 2011 and is now quite dated. The software and our thinking have gone miles beyond what is in the book. Still, the book presents the philosophy behind the development of OOM, and it presents the mathematics behind the binary Procrustes rotation analysis. It also presents several ideas not covered in other papers to date.
