## Automating a DoE and fitting the Model

Hi

I'm working on a bit of software attempting to automate JMP 9 in C#, what I'm attempting to do is create a DoE, fill the data table with my results and then fit the model. I can get as far as generating the DoE and filling the datatable but I'm getting stuck at the final stage of fitting the model. My code looks a little like this (part of a larger class with Response, Factor and Term properties) :

JMP.Application jmp = new JMP.Application();

jmp.Visible = true;

JMP.DOECustom doe = jmp.CreateDOECustom();

foreach (JMPResponse response in this.Responses)

{

}

foreach (JMPContinuousFactor factor in this.Factors)

{

}

foreach (JMPTerm term in this.Terms)

{

}

doe.MakeDesign();

JMP.DataTable dt = doe.MakeTable();

// Do bit's and pieces to fill the table

What I'd like to do next is Fit the model and then (hopefully) extract the various coefficients, t statistics and so on from each of the terms. I can't really find anything obvious in the documentation or the code samples that lets me do this.

Any help appreciated.

## Re: Automating a DoE and fitting the Model

The following pure JSL example may help. This kind of thing is discussed in the Scripting PDF doc under the heading Platform Scripting Notes.

Open( "\$SAMPLE_DATA/fitness.jmp" );

fit_model_object = Fit Model(

Y( :Oxy ),

Effects( :Age, :Weight, :Runtime, :RunPulse, :RstPulse ),

Personality( Standard Least Squares ),

Emphasis( Effect Leverage ),

Run(

:Oxy << {Lack of Fit( 0 ), Plot Actual by Predicted( 1 ), Plot Regression( 0 ),

Plot Residual by Predicted( 1 ), Plot Effect Leverage( 1 )}

)

);

vc = fit_model_object << Get Variance Components();

effnames = fit_model_object << Get Effect Names();

effpvals = fit_model_object << Get Effect PValues();

ests = fit_model_object << Get Estimates();

parmnames = fit_model_object << Get Parameter Names();

randeffnames = fit_model_object << Get Random Effect Names();

stderr = fit_model_object << Get Std Errors();

fit_model_object << Get X Matrix();

fit_model_object << Get XPX Inverse();

Show( effnames, effpvals, ests, parmnames, stderr );

## Automating a DoE and fitting the Model

Thanks for that mpb, suspected that I might have to get down and dirty with JSL. I'll add for the benefit of any future users wandering around these parts that the Automating JMP using C# document has some good information on how to access JSL variables and the like.
