WebHistogram, box plot, normal probability plot, and run order plot of the response: We start by plotting the data several ways to see if any trends or anomalies appear that would not be accounted for by the models. We can see the large spread of the data and a pattern to the data that should be explained by the analysis. WebOn the normal probability plot of the effects, effects that are further from 0 are statistically significant. The color and shape of the points differ between statistically significant and statistically insignificant effects. For example, on this plot, the main effects for factors A, B, and C are statistically significant at the 0.05 level.

WebIn statistics, a P–P plot (probability–probability plot or percent–percent plot or P value plot) is a probability plot for assessing how closely two data sets agree, or for assessing how closely a dataset fits a particular model. It works by plotting the two cumulative distribution functions against each other; if they are similar, the data will appear to be … WebA normal probability plot is a plot that is typically used to assess the normality of the distribution to which the passed sample data belongs to. There are different types of …

WebModel interpretation is a vital step after model fitting. For example, analysis of residual values helps to identify outliers; analysis of normal probability plots shows how “normal” the predictions were across the range of values for the dependent variable. For example, Fig. 7.15 shows a Statistica plot of partial residuals (residuals after effects of other … WebFor example, when pi = 0.5, the Z-score = 0. qnorm (0.5) ## [1] 0.
