Transition of computation time. In each figure, the horizontal axis indicates the sample size N and the vertical axis indicates the average of computation time (sec) for each value of the tuning parameters. On the left, the solid and the dashed line represent the average of computation time via C p and CV, respectively. An extended figure of the average of computation time via C p is drawn on the right
