Section 2 - What is DataFit?

(v4.1) DataFit is a tool used to perform nonlinear and linear regression
analysis (curve fitting) and plotting of data with models containing up
to 9 independent variables. What sets DataFit apart from similar curve
fitting and regression programs is its ease of use.  With the
combination of an intuitive interface, online help and wide range of
features, it is a tool which is used effectively by both experts and
non-experts alike. With DataFit you can:

- Enter your data in a standard spreadsheet interface, import delimited
  data files, or cut and paste data between DataFit and other Windows
  applications.

- Perform nonlinear OR linear regression on data containing up to 9
  independent variables, with models containing up to 20 parameters.
  There are over 150 commonly used scientific, statistical and
  engineering 2D and 3D models that are built in. You can also define an
  unlimited amount of your own models.

- Perform linear OR nonlinear regression on one model at a time that
  you choose from a list, groups of models (built in model groups, or
  define your own), or all of the models available with a simple mouse
  click.  The built in models are grouped together based on the number
  of parameters and the general shape of their curves, so there is no
  need to 'blindly' solve every model.  As models are solved, they are
  sorted automatically according to their goodness of fit. If you
  aren't an expert and aren't sure which model you should use, DataFit
  helps you make this decision.

- View the results, including the fitted parameters along with
  their confidence intervals, input vs. Estimated data, and goodness
  of fit information, all with a simple mouse click.

- Data modification is a snap because the software keeps track of the
  most recently solved models.

- Attach notes to record information and conclusions about the project.

- Save projects along with all of the notes and solution information.
  There is no need to keep re-solving the problem each time you run
  the software.

- Export source code to utilize a model of your choice in a program
  that you have written.  You can export self-documented code in either
  BASIC or C.

- Manipulate raw data or regression models in a built in Data
  Calculator.  The Data Calculator can perform over 70 mathematical
  and statistical operations on curves, discreet data, or numbers.
  The calculator can also perform some special functions, such as
  FFT's and creating a data table based on an equation you type in.

- Create 2D and 3D plots of raw data and/or regression models by simply
  selecting the desired information from a list of available data.
  Each plot is completely customizable, including fonts, ranges, line
  colors and styles, error bars, visibility, et.

- Graphically compare the results of different models and/or data
  on the same plot window.

- Save plots along with all of their customization.

- Copy plots to the Windows clipboard for pasting into other
  applications.
