How to read and update Effect content in the fit model with JSL?

[#1]

Hi folks,

I have several models in the JMP data table, I know how to read the scripts with JSL. Is there any easy way to extract the effect from this script, make changes and replace with a new effect? If Block is inside the model effect, I need to change it into a random effect to run model again with REML. Thank you so much for your help.

Here's an example using Big Class.JMP. 

Fit Model(
	Y( :weight ),
	Effects( :height, :sex, :sex * :height ),
	Personality( "Standard Least Squares" ),
	Emphasis( "Effect Leverage" ),
	Run(
		:weight << {Summary of Fit( 1 ), Analysis of Variance( 1 ),
		Parameter Estimates( 1 ), Scaled Estimates( 0 ),
		Plot Actual by Predicted( 1 ), Plot Residual by Predicted( 1 ),
		Plot Studentized Residuals( 0 ), Plot Effect Leverage( 1 ),
		Plot Residual by Normal Quantiles( 0 ), Box Cox Y Transformation( 0 )}
	)
);

Fit Model(
	Y( :weight ),
	Effects( :height, :sex * :height ),
	Random Effects( :sex ),
	NoBounds( 1 ),
	Personality( "Standard Least Squares" ),
	Method( "REML" ),
	Emphasis( "Minimal Report" ),
	Run(
		:weight << {Summary of Fit( 1 ), Analysis of Variance( 0 ),
		Parameter Estimates( 1 ), Scaled Estimates( 0 ),
		Plot Actual by Predicted( 0 ), Plot Residual by Predicted( 0 ),
		Plot Studentized Residuals( 0 ), Plot Effect Leverage( 0 ),
		Plot Residual by Normal Quantiles( 0 )}
	)
)

In the first model there are two terms and their interaction.

The second model has :sex added as a random effect.

A good way to see the difference in the Model's JSL it to create it without the desired feature and with the desired feature and compare the two.
