The whole point of nonlinear regression is to fit a model to your data, to obtain the best-fit values of the parameters. It does this by minimizing the sum-of-squares. What happens when the data are perfect, so the curve goes right through every point and the sum-of-squares is ze...

This paper is devoted to goodness-of-fit tests for parametric possibly nonlinear heteroscedastic regression models. The test statistic is constructed using a marked empirical process based on residuals. We investigate the consistency of this test statistic and of the estimators needed to compute it. ...
1. We introduced the way of nonlinear curve fitting to analyzing the experiment data by the Origin software. 介绍用Microcal Origin软件进行实验数据非线性曲线拟合的具体方法,并结合实例说明如何寻求经验公式。更多例句>> 2) nonlinear regression of curve 非线性曲面拟合...
The main positive is that nonlinear regression provides the most flexible curve-fitting functionality. The downside is that it can take considerable effort to choose the nonlinear function that creates the best fit for the particular shape of the curve. Unlike linear regression, you also need to ...
I would like to know whether someone has experience with doing nonlinear regression fit with matlab. I have exported the comsol code to matlab and wanna do nonlinear regression fit with matlab. In matlab there is a function called 'nlinfit'. I have tried but failed...and could not understand...
