Fitting nonlinear (quantile) models to linear data.
...particular dataset) tend to result in illogical regression results with
the nlqr package.
To test this, I created artificial datasets that were based on underlying
asymptotic or linear data. When tested with a nonlinear model, the linear
data produces an error (step factor reduced below 'midFactor'--a problem
dealt with previously on this list). This script is below, for interest.
My question is whether this is a problem that I should deal with through
fixing my script somehow, or whether fitting a nonlinear model to data
that may have an underlying linear pattern is inherently stat...
