Closest fit data to a particular formula
...had much luck. Perhaps I am reading the
documentation incorrectly. Here is my current loess line code:

mg$x_c <- predict(mg.lo)
which produces a curve like the attached file loess_curve.png.

curve.. starts high and finishes low but doesn't go below zero and only
decreases. Looking at the arccot(x) definition I can see it as:
arccot x...
