Thanks for your valuable points
I and working on time series dataset for temperature records for 2 years (726 instances). I know that I have insufficient dataset. Below is my class label information:
I want to look for all error measures:
Can I say 1.0733, 1.4616 for Mean absolute error and Root mean squared error good result if the mean (average) value is 17.6 ?!
What is acceptable Mean absolute error and Root mean squared error for a numeric class with mean 17.6 ?
If I want to consider relative errors, what are the acceptable values ?
