Select the graphs to display for Nonlinear Regression

Stat > Regression > Nonlinear Regression > Graphs
Plot of fitted curve with data
Display a fitted curve plot with the raw data.
Display confidence interval
Display the 95% confidence interval bands for the prediction around the fitted curve.
Display prediction interval
Display the 95% prediction interval bands around the fitted curve.
Residual Plots
Use residual plots to examine whether your model meets the assumptions of the analysis. For more information, go to Residual plots in Minitab.
  • Individual plots: Select the residual plots that you want to display.
    Histogram of residuals
    Display a histogram of the residuals.
    Normal probability plot of residuals
    Display a normal probability plot of the residuals.
    Residuals versus fits
    Display the residuals versus the fitted values.
    Residuals versus order
    Display the residuals versus the order of the data. The row number for each data point is shown on the x-axis.
  • Four in one: Display all four residual plots together in one graph.
Residuals versus the variables
Enter one or more variables to plot versus the residuals. You can plot the following types of variables:
  • Variables that are already in the current model, to look for curvature in the residuals.
  • Important variables that are not in the current model, to determine whether they are related to the response.
