- Section 1 - Thank you!
-
- As far as we are concerned, this should be sections 1, 2 and 3.
- This program started out as a personal project, but as a result of the
- almost overwhelming response, it became a real software package.
- This thank you is to you people who have taken the time to register,
- and have taken the time to provide some very useful feedback. For
- those of you who have been with us through the growing pains, we
- dedicate this version to you.

- Section 2 - What is DataFit?
-
- DataFit is a tool which simplifies the tasks of data plotting, curve
- fitting and statistical analysis. What sets DataFit apart from similar
- curve fitting and regression programs is its ease of use. With the
- combination of the 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 version 3.0 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.
-
- - Fit your data to 54 built in commonly used scientific, statistical
- and engineering nonlinear regression models, or define an unlimited
- amount of your own regression models. You can attach descriptions
- to your own regression models, and they are saved for future use.
- Built in models automatically generate initial estimates, and you
- can define rules for user defined models so that initial estimates are
- calculated automatically for them as well.
-
- - 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
- mouseclick. 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 mouseclick.
-
- - 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.
-
- - 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, creating a data table based on an equation you type in,
- or produce a "Normal" (Gaussian) curve based on user entered mean
- and standard deviation.
-
- - Create 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.
