Compare Parameter Estimates

In the Fit Curve platform, the Compare Parameter Estimates option gives results for testing the equality of parameters across the levels of the grouping variable. There is an Analysis of Means (ANOM) report for each parameter, which tests whether the parameters are equal to an overall mean. If the result for a parameter exceeds the decision limits, then the parameter is different from the overall mean. Figure 14.11 shows the ANOM report for growth rate estimates. Select Compare Parameter Estimates from the fitted model’s red triangle menu to add the report.

Figure 14.11 Parameter Comparison for Growth Rate Estimates 

The Analysis of Means red triangle menu contains the following options:

Set Alpha Level

Sets the alpha level for the test.

Show Summary Report

Shows or hides a report containing the parameter estimates, the decision limits, and whether the parameter exceeded the limits.

Display Options

Contains options for showing or hiding decision limits, shading, and the center line. Also contains options for changing the appearance of the points.
