Generalized lambda distribution for flexibly testing differences beyond the mean in the distribution of a dependent variable like body mass index
Abstract
BACKGROUND/OBJECTIVES:
Conventional statistical methods often test for group differences in a single parameter of a distribution, usually the conditional mean (e.g., differences in mean body mass index [BMI; kg/m2] by education category) under specific distributional assumptions. However, parameters other than the mean may of be interest, and the distributional assumptions of conventional statistical methods may be violated in some situations.
