Figure 3: Graphs plotted by the package normalized prediction distribution errors ("npde") for R, for the final model. Quantilequantile plot of the npde versus the expected standard normal distribution (upper left). Histogram of the npde with the density of the standard normal distribution overplayed (upper right). Scatter plot of npde versus observed X (lower left). Scatter plot of npde versus predicted Y (lower right)
