Closest fit data to a particular formula
...on for loess - it seems that I can do this by supplying a
formula.. but I have not had much luck. Perhaps I am reading the
documentation incorrectly. Here is my current loess line code:
mg.lo = loess(y ~ x, mg, span=0.25)
mg$x_c <- predict(mg.lo)
which produces a curve like the attached file loess_curve.png.
and I would like to have a curve "something like" the arccot in the
attached file arccotangent.png (from wikipedia), but all x values are
positive - meaning just the best fit of the sample data to that type of
curve.. starts high and finishes low but doesn't go below zero and on...
