Optimal Data Analysis, LLC
This study assesses the agreement between the number of lambs born to 227 ewes over two consecutive years. Polychoric correlation could not be validly used to assess agreement because underlying distributional assumptions were violated. Requiring no such distributional assumptions, prior analysis via ODA identified moderate, statistically significant agreement. Novometric analysis conducted presently identified the globally-optimal model for this application.
