A log transformation is a relatively common method that allows linear regression to perform curve fitting that would otherwise only be possible in nonlinear regression. For example, the nonlinear function: Y=eB0X1B1X2B2 can be expressed in linear form of: ...
Curve Fitting using Polynomial Terms in Linear Regression Despite its name, you can fit curves using linear regression. The most common method is to include polynomial terms in the linear model. Polynomial terms are independent variables that you raise to a power, such as squared or cubed terms...
MUSASHI:NMR Pulse Width Determination Method by Nonlinear Least Square Curve Fitting We have developed a new method named MUSASHI to determine the 90 deg ~1H pulse width in~1H-NMR in an automated fashion using a nonlinear least square curve fitting algorithm.This method is very robust and ...
The Levenberg-Marquardt method for nonlinear least squares curve-fitting problems The Levenberg-Marquardt method is a standard technique for solving nonlinear least squares problems. Least squares problems arise in the context of fitting a pa- rameterized function to a set of measured data points by...
