Last month we explored how to model a simple relationship between two variables, such as the dependence of weight on height 1. In the more realistic scenario of dependence on several variables, we can ...

In this article we focus on three partial effect sizes for the correlation (r) family of effects: the standardized slope (b), the partial correlation (rp), and the semi-partial correlation (rsp).

Approximations are found to the joint distributions of noncircular and circular partial serial correlation coefficients calculated from residuals from regression on Fourier series. Results for ...
