This is the powerful visualization tool for studying how the response relies on an explanatory variable given the values of other explanatory variables. The plot comprises of a number of panels one of which shows the values of the particular explanatory variable divided into the number of intervals, while the others show the scatter plots of the response variable and an another explanatory variable corre- sponding to each and every interval in the given panel. The plot is checked by moving from left to right through intervals in the given panel, while at the same time moving from left to right and then from the bottom to top through the dependence of the panels. The example shown
