Hi, I'm trying to create the P-P plot of regression standardized residuals using the data from this Pearson test from a previous question similar to the provided example below.

Could you share the steps how to create the plot and which data you use?

How do you test for Homoskedasticity?

Normal P-P Plot of Regression Standardized Residual Dependent Variable: Life Satisfaction 1.0T 0.8- 0.6- Expected Cum Prob 0,4- 0.2- 0.0 0.2 0.4 0.6 0.8 1,0 Observed Cum Prob
