I'm wondering how to go about interpolating a rate if it is between two rates...
To start with, this is what I have now,
So here, the $250,000 has a grouping of C (The grouping can be either A, B, or C, it is just determined to be C from the State)
In my other data, each grouping has a rate - However, this rate is dependent on the amount, in this case, 250000.
Here is data with groups A, B, and C. The left column is the $ in thousands, (so 250000 is 250), and I want to grab the rate in A column.
Question 1: Assuming my $ is 250000, How would I do this?
Question 2: if my $ is in the middle, like 55,000, I would need the rate between the 55 and 75 rate and interpolate it, how would I do this?
Thank you in advance.
Well, What I would Do, I will Plot Column A Versus Your Values To get a Trend Line Like y=mx+c or may be some sort of a polynomial Where y is your Rate So then If I Take X=55, It will Interpolate, I would Take It If R2 is >=0.9 , in this case.
