2. Missing Outlier Data. Normal probability plots don’t tell you how many outliers there are or where they are. You can use ...

Note that the PROBPLOT statement creates a normal probability plot for DIAMETER by default. The nonlinearity of the point pattern indicates a departure from normality. Since the point pattern is ...

Example 55.8: Creating PP and QQ Plots The following program creates probability-probability plots and quantile-quantile plots of the residuals (Output 55.8.1 and Output 55.8.2, respectively).An ...

The full normal distribution table, with precision up to 5 decimal point for probability values (including those for negative values), can be found here. Let’s see some real-life examples.
