WebDistribution Fitting. Given a collection of data that we believe fits a particular distribution, we would like to estimate the parameters which best fit the data. We focus on three such methods: Method of Moments, Maximum Likelihood Method, and Regression. Method of Moments. Exponential Distribution.
