Since 1983 when The MIT Press published the first edition, a recognition of the reality of complex random variation has been pushed by the need to quantify and manage risks in complex systems, says Vanmarcke (Princeton U., US), and pulled by the high-level probabilistic modeling made possible by fast-growing computing power and database size.
Even when equating is conducted under these desirable conditions, the random variation in form-to-form equating, when concatenated over time, can produce substantial shifts in score conversions, that is, scale drift.
When assessing for length effects, we recommend using a binomial GLMM with between-site random variation in both the vessel and length effects.
A correlation coefficient of 0.72 was calculated for the two methods, indicating a fair amount of random variation between the two methods.
