### Customer Question

I have a set of data including a dependent variable (x) and an independent variable (y). X is a percentage and y is a duration (years). Theory suggests that x should decrease as y increases, but it doesn't always. Thus, a three-year old case and a twenty-four year old case may have the same score, but the twenty-four year old case should be much lower. I'm trying to calculate an expected rate of change in y to produce a score indicating how far off expected change each case is. Thus, each dependent variable x can be evaluated according to a constant (C) so that we aren't simply comparing raw scores but are taking y into account.Example:
Case 1 - DV score x = 75, IV score y = 24
Case 2 - DV score x = 90, IV score y = 16.3
Case 3 - DV score x = 40, IV score y = 9.3
Case 4 - DV score x = 25, IV score y = 19.3What's the best way forward to determine what y should be if all cases had the same rate of change? Or is there a better way to standardise the x scores relative to y scores?

Hi,

Do you have to find the regression equation?
