Introducing the Methods Corner
In this issue of Health Services Research, we introduce a new, occasional series, the Methods Corner, which will aim to improve the practice of health services research. The article in this issue, entitled “Interaction Terms in Nonlinear Models” (Karaca-Mandic et al. 2011), describes the best approach for estimating and presenting the results of nonlinear regression models that include interaction terms among the explanatory variables. Although this topic has received attention over the last few years in the economics literature, practice remains suboptimal in many of the articles submitted to our Journal and to other journals in our field.
