Normal probability plot of residuals in excel

WebPlotting position: To construct a probability plot, xi is plotted against F-1 (pi), where pi is the estimate of F (xi), namely the plotting position. Several approaches have been proposed to compute pi. XLSTAT includes the following options: Blom (1958): pi = (i – 0.375)/ (n + 0.25) Hazen (1914): pi = (I - 0.5)/n Weibull (1939): pi = i/ (n + 1) WebWe can obtain a suite of diagnostic plots by using the plot function on the ANOVA model object that we fit. To get all of the plots together in four panels we need to add the par (mfrow=c (2,2)) command to tell R to make a graph with 4 panels 23. There are two plots in Figure 2-9 with useful information for the equal variance assumption.
