Fit data to a power distribution (java)

Question

Much like in Excel where we can take a distribution and make a trendline for it (power law), how can I calculate that in Java for an array of numbers?

Answer 1

The package org.apache.commons.math.optimization.fitting includes CurveFitter and PolynomialFitter that will cover many of the typical excel trend line options. JFreechart includes some support for Regression.
