Hello
I need to find precision recall curve. I am following https://www.mathworks.com/help/stats/perfcurve.html#bunsogv-XCrit to do so.
I change the x and y output type by using Xcrit and Ycrit as mentioned in link. I got same XCrit values after changing its type. Similarly with YCrit.
I run
[XCrit1,tpr,YCrit1,ppv] = perfcurve(Y,diffscore1,'HandGrip');
[XCrit2,ppv,YCrit2,tpr] = perfcurve(Y,diffscore1,'HandGrip'); % code run but
[XCrit3,tp,YCrit3,tp] = perfcurve(Y,diffscore1,'HandGrip'); % code run but
[XCrit4,ecost,YCrit4,ecost] = perfcurve(Y,diffscore1,'HandGrip');
value of XCrit1,2,3,4 are same and YCrit1,2,3,4 are same.
Please tell my mistakes.
Thanks

Changing the names of the output variables does not have any effect. You need to change options passed in. Also, your output variable names suggested that you do not understand the output variables.
[XCrit1, YCrit1] = perfcurve(Y, diffscore1, 'HandGrip', 'XCrit', 'ppv');
[XCrit2, YCrit2] = perfcurve(Y, diffscore1, 'HandGrip', 'XCrit', 'tpr');
[XCrit3, YCrit3] = perfcurve(Y, diffscore1, 'HandGrip', 'XCrit', 'tp');
[XCrit4, YCrit4] = perfcurve(Y, diffscore1, 'HandGrip', 'XCrit', 'ecost');
