precision != accuracy,
correlation != accuracy
let f be a continuous real valued function, let c be a fixed bias constant, let pcc be the pearson's correlation coefficient function.
pcc(f) = pcc(f + c)
f + c is precise, but not accurate
- k2enemy 2y agoThe use of correlation was bothering me too. If your watch always read 2x your actual heartrate, it would have a 100% accuracy under this metric.
- paulryanrogers 2y agoDo you mean 100% precision?
