Which one is the one where when you calculate a percentage change, you use an average of beginning value and ending value for denominator as opposed to usual beginning value?
For example, when you calculate the percentage change from 1 to 2, it would be (2-1)/1=100%. But with above referenced method, it would be (2-1)/1.5=67%.
Was it HPR or one of the calculations from Econ? I can't remember.
Please help.
