- (v3.0) 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 number of your own regression
- 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 mouseclick.
- 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.
-
- - 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,
- data tables, or numbers.
-
- - 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 in the
- same plot window.
-
- - Save plots along with all of their
- customization.
