Spontaneous otoacoustic emissions have long been modeled using self-excited, nonlinear oscillators. The van der Pol oscillator is a common choice, as many of its properties reflect those of SOAEs: both can begin oscillation in the absence of a direct

Chi-Squared Data Analysis and Model Testing for Beginners
The chi-squared method for parameter estimation and model testing is developed for the one-parameter case of a line with a slope but no intercept. Curve fitting is motivated, and several methods for curve fitting are introduced. The chi-squared metho
