I have 2 variables, A and B, and 2 time periods, 1 and 2.
A1= 1
B1= 2
A2= 3
B2= 4
I want to analyze the differences between the ratios of both periods.
A1/B1= 0.50
A2/B2= 0.75
The ratio has increased by 0.25 from period 1 to period 2.
I want to show how much of the increase is due to A and how much of the increase is due to B. For example, I want the end result to be A=0.15, B=0.10 (I know that these numbers are wrong). How should I calculate this? Is this possible?
Thank you!
