I’m not sure i understood how the metric works.
Hourly True value: 50
nmae = abs(40-50)*((24/24)/50)
Which results in 0.2
This seems reasonable
If I multiply these values and treat them as Daily values:
Daily True Value: 1200
nmae = abs(960-1200)*((24/7)/1200)
Which results in 0.6857143
is this correct?
The daily error seems off to me.
