Case Studies of Curve Fitting Pitfalls

The case studies that I used for this paper are actually taken from my prior work at Jandel. During my three years there, I managed to find a lot of examples of curve fitting in action.

The main goal is to so over these three points for each case study:

1) What the pitfall is

2) How to determine if you've run into the pitfall and what steps can be taken to remedy the situation

3) How to avoid the pitfall
