I am working on a project and need to do something like this:
for 3 different time period like 30, 40, 50 days, I have three different
interest rates 1,1.2, 1.5. I need to obtain a trendline with y=interest rate
and x=time.Hopefully, the function will be looks like y=a*x+b*x^2. Then I am
gonna plug in a new period of time(like 45 days) and get a new interest rate.
I can use regression to get the parameter, but how can I keep the parameter
from regression and use this function to calculate out a
