Mean absolute percentage error
Fri, 05/22/2020 - 11:33 am
I have two waves that I want to compare in order to determine how different/similar they are. One wave has 2000 points and the other has 236 points. I wanted to use the mean absolute percentage error as my metric of difference but I think that requires the two waves to have the same number of points. In addition to that, the large wave is defined via an x-value of 270 to 320 in evenly spaced increments of 0.025 while the smaller wave is defined via an x-value of 270 to 348.99 in nonuniform steps.
What's a good way to go about consolidating their sizes? Does IGOR have a built-in function that allows me to readily compare them?
