Regression analysis, especially nonlinear regression, is an essential tool to analyze
biological (and other) data. Many researchers use nonlinear regression more than any
other statistical tool. Despite this popularity, there are few places to learn about nonlinear
regression. Most introductory statistics books focus only on linear regression, and entirely
ignore nonlinear regression. The advanced statistics books that do discuss nonlinear
regression tend to be written for statisticians, exceed the mathematical sophistication of
many scientists, and lack a practical discussion of biological problems.
