How to extract Parameter Estimates of Reciprocals (i.e. make into data table) derived from Bivariates Fit Special?

First of all, my Bivariate Analysis works well. Unfortunately "Make Into Data Table"-Reporting doesn't (meaning, jmp does not create any output table).

I applied the following script:

dt = Current Data Table ();

biv = dt << Bivariate(

Y( :Y ),

X( :X ),

Fit Special(

xTran( "Reciprocal" ),

{Line Color( "BlueCyan" ), Line Width( 2 )}

));

//Note: Parameter Estimates are in TableBox3

rep = Report (biv [1]) [TableBox(3)] << Make Combined Data Table;

Do you know the correct scipt for exporting the parameter estimates to a new table?

I really would appreciate your help so much!

You were very close . . .

NamesDefaultToHere(1);

// Data

dt = New Table ("X and Y",

NewColumn("X", Numeric, Continuous, Formula(RandomNormal())),

NewColumn("Y", Numeric, Continuous, Formula(RandomNormal())),

NewColumn("By", Numeric, Nominal, Formula(RandomInteger(1, 3))),

AddRows(100)

);

// Biveriate analysis: biv is a list, one item for each level of the 'By' variable

biv = dt << Bivariate(

Y( :Y ),

X( :X ),

By( :By ),

Fit Special(

xTran( "Reciprocal" ),

{Line Color( "BlueCyan" ), Line Width( 2 )}

)

);

// A reference to the report layer: bivRep is also a list

bivRep = biv << Report;

// 'Make Combined Data Table' avoids having to message to each item in 'bivRep'

dt2 = bivRep [1] [TableBox(3)] << Make Combined Data Table;

Hi,

I am trying the solution proposed by Ian_JMP, but I am unable to extract the parameters from the 'bivRep' object. I am regressing Y by X and I have 5 'By' variables.

My log shows the following:

bivRep = biv << Report;
/*:

List( 5 elements ) assigned.

//:*/
dt2 = bivRep [1] [TableBox(3)] << Make Combined Data Table;
/*:

Cannot subscript Display Box in access or evaluation of 'bivRep[1][Table Box(3)]' , bivRep[1][/*###*/Table Box( 3 )]

In the following script, error marked by /*###*/
dt2 = bivRep[1][/*###*/Table Box( 3 )] << Make Combined Data Table

So I can get a list 'bivRep' with 5 elements (one for each by variable I presume), but the the indexing of the elements within the list doesn't work. What am I doing wrong?

Thanks.
