NLREG -- Nonlinear Regression Analysis Program NEWS • NLREG has been selected as the 'Editor's Pick'. • NLREG is in use at hundreds of universities, laboratories, and government agencies around the world (over 20 countries). • If you have categorical variables, you may want to use a Decision Tree to model your data. Check out the. • You also should check out the program that automatically scans Usenet newsgroups, downloads messages of interest to you, decodes binary file attachments, reconstructs files split across multiple messages, and eliminates spam and duplicate files.

NLREG -- Nonlinear Regression and Curve Fitting NLREG is a powerful statistical analysis program that performs linear and nonlinear regression analysis, surface and curve fitting. NLREG determines the values of parameters for an equation, whose form you specify, that cause the equation to best fit a set of data values. NLREG can handle linear, polynomial, exponential, logistic, periodic, and general nonlinear functions.

Unlike many 'nonlinear' regression programs that can only handle a limited set of function forms, NLREG can handle essentially any function whose form you can specify algebraically. NLREG features a full with a syntax similar to C for specifying the function that is to be fitted to the data. This allows you to compute intermediate work variables, use conditionals, and even iterate in loops. With NLREG it is easy to construct that change form over different domains. Since the includes arrays, you can even use tabular look-up methods to define the function. Here is an example of an NLREG program for fitting a damped sine wave to some data: Title 'Damped pendulum motion'; Variables Time,X; Parameter A,alpha,w,offset,Phase; Function X = A*exp(-alpha*Time)*sin(w*(Time-Phase))+offset; Plot; Data; [ data goes here ] NLREG performs analysis and curve fitting, 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 = Amplitude*sin(Freq*X+Phase) + Growth*exp(X) + Offset; Where 'Amplitude', 'Freq', 'Phase', 'Growth', and 'Offset' are parameters whose values are to be determined by NLREG. Another advantage of handing the function in true nonlinear form is that the minimization of the sum of squared residual values (i.e., 'least squares') is based on the true nonlinear value rather than some linearized transformation. In addition to computing the optimal values of the parameters to best fit the function to the data, NLREG can generate of the data points and the fitted equation.

In addition, it can plot the distribution of residual values and produce a normal probability plot. NLREG also computes auxiliary statistics such as Student's t, Prob(t), F, Prob(F), Durbin-Watson, and, optionally, correlation and covariance matrices. The can fit up to 5 variables and parameters to the data observations. The can handle up to 2000 variables and parameters. In addition, the Advanced version can generate such as shown here: In addition to performing classic nonlinear regression, NLREG can be used to of a general multivariate, nonlinear function.

It can also be used in a special form where the independent variable is omitted; an interesting application of this is ' where a circle is fitted to a set of data points. And versions of NLREG are available for applications that want to call NLREG as an 'engine' to perform regressions. To see an example Visual Basic program that calls the NLREG COM Library. NLREG has been validated using the developed by the National Institute of Standards and Technology.

General • Free add-in for Excel that performs multivariate descriptive data analysis and linear and logistic regression analysis with a novel output and interface design. • Written in Visual Basic, the program file is less than 1M in size and it can be launched on an as-needed basis or placed on the Excel add-ins menu. • The linear regression version now runs on Macs (in the native Mac version of Excel) as well as on PCs.
