Specify default settings for residual plots in ANOVA, Regression, and DOE. The changes you make to the defaults remain until you change them again, even after you exit Minitab.
Note
To specify settings for residual plots in Time Series, in Minitab, choose
File > Options > Individual Graphs > Residual Plots for Time Series.
Conditional regular: Conditional residuals are the difference between the conditional fits and the observed values in the sample data. Use the conditional residuals to check the normality of the error term.
Conditional standardized: Plot the standardized versions of the conditional residuals. If an observation has a standardized residual greater than 2, it may be an outlier in your data.
Marginal regular: Marginal residuals are the difference between the marginal fits and the observed values in the sample data. Use marginal residuals to evaluate whether the marginal equations can represent the mean responses of y well at different levels of the fixed effect terms.
Marginal standardized: Plot the standardized versions of the marginal residuals. If an observation has a standardized residual greater than 2, it may be an outlier in your data.
Four in one: Display a histogram of residuals, a normal probability plot of the residuals, a plot of residuals versus fits, and a plot of residuals versus order in a single layout.
Histogram of residuals: Display a histogram of the residuals.
Normal plot of residuals: Display a normal probability plot of the residuals.
Residuals versus fits: Plot the residuals versus the fitted values.
Residuals versus order: Plot the residuals versus the order of the data. The row number for each data point is shown on the x-axis (for example, 1 2 3 4... n).
Include Anderson-Darling test with normal plot
Display the Anderson-Darling statistic on the normal probability plot of the residuals. The statistic is displayed only for models that have three or more degrees of freedom for error. For more information, go to The Anderson-Darling statistic.
