Introduction to CurveFitter

CurveFitter is a powerful tool for performing statistical regression analysis, allowing users to estimate the values of parameters for various types of functions, including linear, multivariate, polynomial, exponential, and nonlinear functions. This process, also known as curve fitting, determines the values of the parameters that cause the function to best fit the observed data provided by the user. In this article, we will explore the capabilities of CurveFitter, its features, and how it can be used to analyze complex data.

Key Features of CurveFitter

CurveFitter gives scientists, researchers, and engineers the power to find the ideal model for even the most complex data, including equations that might never have been considered. The software allows users to build equation sets that can include a wide array of linear and nonlinear models for any application. Some of the key features of CurveFitter include:

User-defined equations: Users can define their own equations of up to nine parameters and eight variables.
Linear equations: CurveFitter supports linear equations, which are commonly used in various fields, including physics, engineering, and economics.
Nonlinear exponential, logarithmic, and power equations: CurveFitter also supports nonlinear equations, including exponential, logarithmic, and power equations, which are commonly used in fields such as biology, chemistry, and physics.
38-digit precision math emulator: CurveFitter includes a 38-digit precision math emulator, which allows users to properly fit high-order polynomials and rationals.

Graphical Review of Curve Fit Results

Once the data have been fit, CurveFitter automatically sorts and plots the fitted equations by the statistical criteria of Standard Error. A residual graph, as well as parameter output, is generated for the selected fitted equation within the Review Curve Fit window. This allows users to visually inspect the results and determine the best fit for their data.

Ease of Use

CurveFitter takes full advantage of the Windows user interface to simplify every aspect of operation, from data import to output of results. Users can import data from txt format, create a custom equation set, and start the automatic fitting process with a single mouse click. CurveFitter is highly intuitive, easy-to-use, and remarkably simple to learn, making it accessible to users of all skill levels.
