An illustrative example of the estimated CDFs, F∗, under RQRs (top panels) and MQR (bottom panels). Panels in the left column present the residuals under the true model and panels in the right column present the residuals under the wrong model. The curved grey lines correspond to the theoretical CDF of F(k|xi)versusxi at each value of k. The points are the randomized CDFs \(F^{\ast } (y_{i};\hat {\mu }_i,\hat {\phi }, u_{i})\) with each colour corresponding to a unique value of yi
