Editor > Add > Distribution Fit
Use to fit a distribution to your data to help you determine whether the data can be adequately modeled by the selected distribution.
After creating a graph, you can change the fitted distribution, add groups, and change the fitted line attributes (see Editing Data Fits Overview).
Distribution: Choose a distribution.
Historical parameters: Enter historical estimates of the distribution parameters. Minitab displays the necessary parameters, which depend on the chosen distribution. These parameters may include Mean, Standard Deviation, Location, Shape, Scale, or Threshold. If you do not enter historical estimates, Minitab estimates the parameters from the data. You can enter some historical estimates and have Minitab estimate the other parameters. See Distribution parameters for restrictions.
