DOI: 10.1002/sim.8505
Abstract: The statistical practice of modeling interaction with two linear main effects and a product term is ubiquitous in the statistical and epidemiological literature. Most data modelers are aware that the misspecification of main effects can… read more here.

DOI: 10.1080/03610926.2017.1376091
Abstract: ABSTRACT In this paper, we propose two methods of constructing row-column designs for factorial experiments. The constructed designs have orthogonal factorial structure with balance and permits estimation of main effects with full efficiency. read more here.

DOI: 10.1080/15598608.2016.1197868
Abstract: A new method to generate designs for estimating main effects and two-factor interactions of two-level attributes from choice experiments is presented for the situation where the choice sets are pairs and the alternatives are specified… read more here.

DOI: 10.1093/her/cyaa052
Abstract: Iceland has witnessed a dramatic decline in adolescent substance use that may be partly the result of efforts related to the Icelandic prevention model (IPM). We sought to test risk and protective factor assumptions of… read more here.

DOI: 10.3389/fpsyg.2019.02986
Abstract: Graphs are useful tools to communicate meaningful patterns in data, but their efficacy varies considerably based on the figure’s construction and presentation medium. Specifically, a digital format figure can be dynamic, allowing the reader to… read more here.

DOI: 10.5055/jem.0569
Abstract: Emergency department (ED) overcrowding is a national problem that is associated with ambulance diversion, decreased patient and provider satisfaction and poor patient outcomes. This study presents a novel approach to modeling the relationship between time… read more here.
