Receiver Operating Characteristic (ROC) Curves with Excel Pivot Table Function

[@StephenRaftery3141]

This is very useful. I particularly like the way you use a Pivot Table to generate the Sensitivity and Specificity values

Could you please explain how did you calculate sensitivity and specificity values

Hi Can you please tell us if two x axis values can be analyzed on the same roc

[@jusarquis]

Hi, this is so easy, thank you so much! I had the coordinates but didn't know how to plot the curve. One question, how can I insert the middle line in the graphic? Thank you soooooooooo much!!!

[@stokesbaker5907]

What do you mean by midline?

[@jusarquis]

@@stokesbaker5907 I meant the line of the null hypothesis, I found out how to do it, thank you!

[@JoaoGuilherme-og6vg]

Great tutorial! Thank you. Is there a way to get the best accuracy cut off, not necessarily corresponding to one of the BMI values, but also in between them? For example, could the best accuracy point be 34.6, for example, and some automatic calculation bring this information?

[@stokesbaker5907]

I will look into your question and respond soon. SSB

[@coolscientish1085]

Thank you for your reply but I am still confused, in a case where you have a gold standard and the device you are testing, which one has results that are labelled as healthy/not healthy (like autopsy results), and which one has values (like BMI)

Thankyou Mr. Baker!!

great explanation! thank you :)

[@highnono]

Thank you very much! Do you know how to calculate the area bellow the ROC curve using Excel?

[@stokesbaker5907]

Old timer's trick is to use a see scale to estimate the area under the curve. Cut out a know are (e.g. 10 x 10 = 100 sq units). Then cut out the desired area under the curve. The first is used to convert surface area to grams. The mass of area under the curve divide by g/sq units = surface area under the curve.

HI IS AUTOPSY RESULTS THE CONTROLS OR ?

[@stokesbaker5907]

The autopsy results are that are used to determine sensitivity and specificity.
