Emphasis Options for Standard Least Squares
Emphasis Options for Standard Least Squares
The options in the Emphasis menu control the type of plots that you see as part of the initial analysis
report for the Standard Least Squares personality.
Table 2.6 Description of the Emphasis Options
Effect Leverage
Effect Screening
Minimal Report
Starts by showing leverage and residual plots for the whole model. You can
then request effect details and other statistical reports. This is the most
detailed option.
Shows whole model information followed by a sorted parameter estimates
report with a graph and the Prediction Profiler. This option can be
appropriate when you have many effects and do not want to see details until
you discover which effects are stronger and which are weaker. This is the
recommended method for screening designs, where there are many effects
and few observations, and the quest is to find the strong effects, rather than
to test significance.
Suppresses all plots except the regression plot. You request the options that
you want from the platform red triangle menu. This is the least detailed
option.
Model Specification Options
Table 2.7 describes the options in the red triangle menu next to Model Specification.

Center Polynomials
Set Alpha Level
Save to Data Table
Save to Script Window
Causes a continuous term participating in a crossed term to be centered by
its mean. Exceptions to centering are effects with coded or mixture
properties. This option is important to make main effects tests be
meaningful hypotheses in the presence of continuous crossed effects.
Sets the alpha level for confidence intervals in the Fit Model analysis.
Saves your specifications in the Fit Model launch window as a script that is
attached to the data table. The script is named Model.
For details about JSL scripting, see the JMP Scripting Guide.
Outputs your specifications in the Fit Model launch window to a script
window. You can save the script window and recreate the model at any time
by running the script.
