Partial AUC

HyeWonJung

My customer wants to caculate the partial AUC for specific time points on various models (sigmoids, pk.,) fitted in Fit curve .

To calculate the partial AUC,

I thought , subset the dataset with x:grid time y=predictiors to include only the desired time interval and then run the Total AUC add-in.

But I want to know is there any built-in partial AUC platform in JMP .

If they have the formula then the integrate function in the scripting index will do what they're after:

If they've only got the data data then the trapezoidal rule is is your best bet. You should also chime in on this internal wishlist item since this is a customer request: https://community.jmp.com/t5/Internal-Wish-List/Area-Under-the-Curve-and-Normalization-of-Curve/idi-p/631203

Thank you for sharing the script. and I will upload this into the internal wish list!

Hi @HyeWonJung , The customer may also be interested area under Precision-Recall curves, which are available by default in 18 Pro with the XGBoost and Torch add-ins.

Thanks for submitting this request. Not an ideal solution, but if the user is on JMP Pro this is possible in FDE. You ask for peak detection and then manually define a peak over the range of integration. The trapezoid rule AUC is provided in the Peak Summaries table. (Thanks to @clay_barker for sharing this info and example.)
