Text data editor

Cut-and-paste text or edit data here

Comma conversion

Convert commas to spaces (1,2,0,3 yields 1 2 0 3)

Use comma as decimal separator (1,203 = 1.203)

Remove commas from text (1,2,0,3 yields 1203)

Weighted fitting

Standard Unweighted Fitting: no weights required

Weighted Fitting: each data point requires a weight

Text data

This data is provided as an example, cut and paste as needed to model your data. All lines of text that do not begin with a number are ignored. Weighted fitting requires an additional number to be used as a weight when fitting. The site does not calculate any weights, which are used as: error = weight * (predicted - actual) You must provide any weights you wish to use.

Graph scaling and lin/log control

Here you can choose the scaling of the data plots and the 3D scatterplots. Log plots require data values greater than zero.

Graph and Animation size

Here you can choose the size of the graphs. Smaller size files load quickly, with less resolution while large files show more resolution but load more slowly.

Hold Coefficients Constant

Here you can enter values to hold coefficients constant during fitting.
Leave the entry field blank to let the coefficient fit normally.

Note that coefficient bounds are overridden by holding a coefficient constant.

z = ay³ - byx² + Offset

Coefficient	Value
a
b
Offset

Estimated Initial Coefficients

Here you can enter values for initial parameter estimates.

Few users will need this section, as the site estimates initial parameters using the Differential Evolution genetic algorithm for both non-linear equations and non-Gaussian fitting targets.

z = ay³ - byx² + Offset

Coefficient	Value
a
b
Offset

Coefficient Bounds

Here you can enter coefficient upper and lower bounds. Leave the entry fields blank to let the coefficients fit without bounds.

Note that holding a coefficient constant overrides these bounds.

z = ay³ - byx² + Offset

Coefficient	Upper Bound	Lower Bound
