Specify default settings
for residual plots in ANOVA, Regression, DOE, and the
Linear
Regression and Binary Logistic
Regression analyses for the Predictive Analytics
Module. 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.
