If these assumptions are satisfied then ordinary least squares regression will produce unbiased coefficient estimates with the minimum variance. Examining residual plots helps you determine whether the ordinary least squares assumptions are being met.

163 - Unspecified Probabilities.

. For more information go to. The procedure is similar to the one that you learned earlier in this lesson for constructing a confidence interval for a proportion. 165 - Using Minitab to Lighten the Workload.

Here you will learn how to use Minitab to construct a confidence interval for a mean. 164 - Continuous Random Variables. At the bottom of this page you will find instructions for using Minitab with.

A residual plot is a graph that is used to examine the goodness-of-fit in regression and ANOVA. S is measured in the units of the response variable and represents the how far the data values fall from the fitted values. Verify that your test has enough power to detect a difference that is practically significant.

The following example walks through this procedure when data are in a Minitab work. 161 - The General Approach. 162 - Extension to K Categories.

171 - Test For Homogeneity. Examine the goodness-of-fit statistics in the model summary table. 172 - Test for Independence.

S Use S to assess how well the model describes the response. Which residual plots are included.
