The powers of Inline graphic (black solid), Inline graphic (grey solid), Pearson correlation (grey circles), distance correlation (black dashed), the method of Heller et al. (2016) (black dotted) and Inline graphic (black circles) for testing independence between Inline graphic and Inline graphic when the underlying true functional relationships are linear, quadratic, cubic, radical, low-frequency sine, triangle, high-frequency sine, and piecewise constant. The horizontal axis represents Inline graphic, a monotone function of the signal-to-noise ratio, and the vertical axis is the power. We chose Inline graphic and performed 1000 replications for each relationship and each Inline graphic value.
