Webb23 nov. 2024 · The histogram and the normal probability plot of the residuals are often used to check if it is reasonable to assume the errors have a normal distribution and detect outliers. This histogram is the most commonly used to … WebbThe residuals are simply the error terms, or the differences between the observed value of the dependent variable and the predicted value. If we examine a normal Predicted Probability (P-P) plot, we can determine if the residuals are normally distributed. If they are, they will conform to the diagonal normality line indicated in the plot.

When sample size is large: draw separate plot for each treatment group. The normal probability plot is a graphical technique to identify substantive departures from normality. This includes identifying outliers, skewness, kurtosis, a need for transformations, and mixtures. Normal probability plots are made of raw data, residuals from model fits, and estimated parameters.
