Homework Statement
I need to fit a model to some data, where y = systolic blood pressure and x = time in weeks. The problem is, all of the 'usua' trendline options on Excel produce awful R squared values. Is there some other method I can do to fit a different sort of model that would be accurate?
Homework Equations
None that I know.
The Attempt at a Solution
Only thing I can put here are the graphs, but that seems a little pointless.
