• How to add data values to a table in a for loop using Select Columns Where to make a new overall data table of target data

  For( date = date_array << First, !Is Empty( date ), date = date_array << Next( date ), //looping through date_array's keys is clunky but done this way in JMP dt << Select Columns( :Timepoint, :Target Channel, :Run date ), Where(:Timepoint == date); dt << Subset( ( Selected Rows ), Output Table Name( "Subset" ));
);I wish to add, progressively, through each iteration of a for loop, data specifie...

• help with disallowed combinations for Custom DOE

  Hi, I'm trying to design a split-plot experiment (4 hard-to-change (HTC) and 1 easy-to-change (ETC) variable) that involves existing hardware, so I've set the role of the four HTC variables as "discrete numeric" in the design.  Each of HTC variables (let's call them A, B, C, D) has three values representing the low, middle, and high levels (let's call the values 1, 2, 3 - but they are numeric, not...

• Target Index/alternatives for Process Screening

  For some dumb reason I was thinking that Target Index normalized on the Spec window, and I'm realizing now that it normalizes on the within sigma, which is a problem as I have a lot of mathematically significant signals that aren't practically significant.  So, couple quick questions.    If you provide a specified sigma will the Target Index use that instead of within?  That will at least standard...

• Extracting slope from Fit Special

  I have two variables X & Y that I fitted a line with the y - intercept constrained to 0.I need the slope value from this line for a subsequent calculation.Is there anyway to save this slope value in a column so that I can use it for the subsequent calculation.Bivariate(

  X( :X ),

• Terms in parameter estimates for two-way interactions of coded factors are being given as e.g. (EtOH + 0.1)*(n-PrOH-0.1)

  I'm trying to work through an example out of Goos and Jones (Ch 3), where they've set up a DoE screen and model of select two-way ineractions. All factors except "Block" are continuous, and the factors are coded as -1 and +1 for the two levels tested. When fitting the model, I'm confused that the Parameter Estimates pulldown gives each interaction term not as e.g. EtOH*n-PrOH, but rather as (EtOH ...
