Using no weighting is most appropriate when no known relationship exists between the variances of the data around the fitted curve and the y values of the points. However, it is often the case in experiments that it is known that the uncertainty is a certain percentage of the y value; in this case, weighting the points by 1/y^2 can prevent the larger scatter at higher y from adversely ...
CurveExpert allows you to use up to 19 parameters, lettered a..s. All arithmetic operations are valid, as well as the symbol ^ to raise a number to a power. Here is an example of what you could enter in the Define User Model dialog box: a\*x\*log(b+x)+c^x. Note that there is no need to enter the ‘y=’ before the function – only the right ...
28 de abr. de 2024 · 1.3. CurveExpert Professional is a cross-platform solution for curve fitting and data analysis. Data can be modelled using a toolbox of linear regression models, nonlinear regression models, smoothing methods, or various kinds of splines. Over 60 models are built-in, but custom regression models may also be defined by the user.
Right click on the graph preview window (the graphing area in the main window of CurveExpert), and make sure that “Enable Animations” is off. By default, CurveExpert ships with this option enabled in order to provide live feedback on changes being made to the curve fit as it is being calculated.
