Package org.apache.commons.math3.fitting Description

Classes to perform curve fitting. Curve fitting is a special case of a least-squares problem where the parameters are the coefficients of a function

f

whose graph

y = f (x)

should pass through sample points, and were the objective function is the squared sum of the residuals

f (x_{i}) - y_{i}

for observed points

(x_{i}, y_{i})
