What inspired this wish list request?
For DOE analysis (Fit Model) people do not understand why the blue bar is for a pvalue threshold at 0.01 (and not 0.05)
(in DOE, small sample, not a lot of factors)
What is the improvement you would like to see?
Can we set the blue bar with a default pvalue threshold at 0.05?
And can we have an option to change it?
Why is this idea important?
People sometimes remove significant effects (e.g. pvalue=0.03, below the blue bar)
I assume you are talking about the reference line that used in the plot of LogWorth by Effect in the Effect Summary. It is set at a fixed value of 2, which corresponds to a log worth of -Log10(0.01).
You can change the reference line with JSL, by sending the message << Reference line(value) to that display box (a plot col box).

dt=Open( "$SAMPLE_DATA/Design Experiment/Reactor 20 Custom.jmp" );
fm=dt << Fit Model(

:Temperature * :Concentration

)
)}
)
);
pcb=report(fm)["Effect Summary"][Plot Col Box(1)];
// set the reference line to the logWorth equivalent to a p-value of 0.0001
pcb << set reference line(-log10(0.0001));Hello @francois_berger , thank you for your request. We will discuss this wish internally and keep you informed. And thanks @MathStatChem for your workaround.
