I have a sequence of ground truth and a sequence of measured values.
Ground truth sequence: 4,5,3
Measured values sequence: 5,4,5
I would like to calculate the relative error of the whole sequence. In other words, I am interested in how much different the Measured sequence is from Ground truth sequence.
Currently, I am taking the average of individual relative errors as follows:
$$ \frac{ \frac{|4-5|}{4} + \frac{|5-4|}{5} + \frac{|3-5|}{3}} {3}$$
I don't know if it is the correct way. Can someone please guide me the best way to compute it?
