The curve-fitting technique used in this app is based on regression analysis by the method of least squares. The free version fits a straight line through a data-set using least squares analysis. One In-App purchase is required to fit the other equations to the data set: ...
Solve nonlinear least-squares (curve-fitting) problems in serial or parallelNonlinear least-squares is solving the problem min(∑||F(xi) - yi||2), where F(xi) is a nonlinear function and yi is data. The problem can have bounds, linear constraints, or nonlinear constraints. These problems...
