Boxplots of p-values from weighted linear regression and rank-ordered logit model. Boxplots show the p-values from testing β1 = 0 based on concordance (C) and discordance (D) of the signs of the estimated β1 from all three approaches: weighted linear regression on log-transformed rates (LR-ln) and on untransformed rates (LR-un), and the rank-ordered logit (ROL) model on rates
