A Simulation Study Using a Mixed Model Framework to Analyze the Impact of Sample Size and Variability on Type I Error

Xiaoxue Gu, Curt Doetkott & Rhonda Magel · Asian Journal of Probability and Statistics · 2022

Aims: This simulation study was conducted to check the validity of a MIXED model’s statistical inference when violating the underlying assumptions – normality of random errors when there are unbalanced group sizes and inequality of variance of errors [Scheffe, 1959]. Study Design...
