**Features of CurveFitter:**

CurveFitter is a
powerful statistical analysis program that performs linear and
nonlinear regression analysis (i.e. curve fitting). CurveFitter
determines the values of parameters for an equation, whose form you
specify, that cause the equation to best fit a set of data values.
CurveFitter can handle linear, polynomial, exponential, and general nonlinear functions. Unlike many "nonlinear"
regression programs that can only handle a limited set of function
forms, CurveFitter can handle essentially any function whose form you can
specify algebraically.

CurveFitter 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

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, CurveFitter generates plots of the data points and
the fitted equation. In addition, it plots the distribution of residual values.
