**The polynomial regression method**- License: Shareware

This code implements the 1D polynomial regression method. It uses the least square method for the finding of regression polynomial coefficents. Outputs of the script are polynomial regression coefficients, residuals, the sum of squared errors, the determination index and the graphical comparison of the regression model and input data..

**clickfit_OH for curve fitting by eye/hand**- License: Freeware
- Price: 0.00

clickfit_OH.m lets you mouse-click a series of datapoints on top of a (noisy) scatterplot and returns a spline or polynomial regression through the clicked dataseries. In addition the clicked series itself is returned. clickfit_OH.m uses an altered version of ginput.m (ginput_OH.m) that from the first click onward connects the mouse-pointer to the previous mouse click location by a line. USES: * ginput_OH by Oscar Hartogensis (inlcuded in zip-file) which includes the selectable cursor pointer option from MYGINPUT by F. Moisy (../fileexchange/12770-myginput) * Uses (but will function without): --> splinefit.

**Movingslope**- License: Freeware
- Price: 0.00

The gradient function in Matlab allows you to compute the slope of a curve along its entire length. But if your curve is a noisy one, then gradient will also be noisy. In this event one might desire to fit a moderately low order polynomial regression model in a sliding window, then differentiate that model. (Like a Savitzky-Golay filter.) All of this can be done efficiently in Matlab using filter. Note that this tool does not constrain the length of the support to be even or odd. Also, this tool uses pinv to generate the filter coefficients - a more stable and accurate methodology than does the sgolay tool on the file exchange.

**Regression Analysis - DataFitting**- License: Shareware
- Price: 15.00

DataFitting is a powerful statistical analysis program that performs linear and nonlinear regression analysis (i.e. curve fitting). DataFitting determines the values of parameters for an equation, whose form you specify, that cause the equation to best fit a set of data values. DataFitting can handle linear, polynomial, exponential, and general nonlinear functions.

DataFitting performs true nonlinear regression analysis, it does not transform the function into a linear form. As a result, it can handle functions that are impossible to linearize such as:

y = (a - c) * exp(-b * x) + c

DataFitting gives students, teachers, engineers, researchers and other professionals the power to find the ideal model for even the most complex data, by putting...

**Non-linear regression GUI**- License: Freeware
- Price: 0.00

The non-linear regression problem (univariate or multivariate) is easily posed using a graphical user interface (GUI) that solves the problem using one of the following solvers: - nlinfit: only univariate problems. - lsqnonlin: can deal with multivariate problems (more than one dependent fitting variable, ydata is a matrix). - patternsearch: this solver is useful to obtain a good start point, before using nlinfit or lsqonolin; this way, the global minimum is determined easier. Data is introduced in the GUI as vector or matrix from the workspace. The model to be fitted must be written in an M-file in vectorized form: ypred = model(x,xdata) ypred is a column vector (univariate problem) or matrix (multivariate problem) with the model response (observations in rows).
