is a powerful statistical analysis program that performs linear and nonlinear regression analysis and curve fitting.

In depth

A closer look at NLREG

It 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, multivariate, polynomial, logistic, and general nonlinear equations. You specify the form of the equation using normal algebraic notation. NLREG includes a rich set of built-in library functions such as trig, probability, exponential, log, Bessel, etc., that you can use in the equation being fitted to the data.

For advanced applications, NLREG includes a programming language that can be used to describe a general mathematical model to be fitted to the data. This language has a syntax like C and includes conditionals, looping, and arrays.

In addition to fitting the equation to the data, NLREG determines a variety of statistics including confidence intervals, t and F statistics, and Durbin-Watson test for autocorrelation. It can also plot the data and fitted equation.

It also includes a 60 page manual that explains regression analysis and gives many examples. NLREG is in use at hundreds of universities, laboratories, and government agencies in over 20 countries around the world.
