Initial Plot of Data

Plot of Data

The first step in fitting a nonlinear function is to simply plot the data.

This plot initially shows a fairly steep slope that levels off to a more gradual slope. This type of curve can often be modeled with a rational function model.

The plot also indicates that there do not appear to be any outliers in this data.
