Templeton and Burney (2017) proposed a two-step normality transformation as a remedy for non-normally distributed data, which are commonly found in AIS research. We argue that, rather than transforming the data toward normality, researchers should first seek to analyze and understand the sources of non-normality. Using simulated datasets, we demonstrate three sources of non-normality and their consequences for regression estimation. We then demonstrate that the two-step transformation cannot solve any of these problems and that each source of non-normality can be handled with alternative, existing techniques. We further present two empirical examples to demonstrate these issues with real datasets.

Unique continuation of the normal operator of the X-ray transform and applications in geophysics
Ilmavirta, Joonas; Mönkkönen, Keijo (Institute of Physics, 2020)We show that the normal operator of the X-ray transform in $\mathbb{R}^d$, $d\geq 2$, has a unique continuation property in the class of compactly supported distributions. This immediately implies uniqueness for the X-ray ... -
Eight Simple Guidelines for Improved Understanding of Transformations and Nonlinear Effects
Rönkkö, Mikko; Aalto, Eero; Tenhunen, Henni; Aguirre-Urreta, Miguel I. (SAGE Publications, 2022)Transforming variables before analysis or applying a transformation as a part of a generalized linear model are common practices in organizational research. Several methodological articles addressing the topic, either ... -
Early Life Influences on Hearing in Adulthood : a Systematic Review and Two-Step Individual Patient Data Meta-Analysis
Dawes, Piers; Newall, John; Graham, Petra L.; Osmond, Clive; von Bonsdorff, Mikaela B.; Eriksson, Johan Gunnar (Lippincott Williams & Wilkins, 2022)Objectives: Adverse prenatal and early childhood development may increase susceptibility of hearing loss in adulthood. The objective was to assess whether indices of early development are associated with adult-onset ... -
