Section 1 - Description and Capabilities of DataFit

DataFit is a science and engineering tool that simplifies the tasks
of data plotting, regression analysis (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 that is used effectively by both beginners and experts. Main
features of DataFit include:

- Intuitive interface - most regression software packages take a
  programming type approach, meaning that you tell the program what to
  do in a pseudo-code programming language. This approach forces you to
  remember many commands, and the proper command syntax. With DataFit,
  the program is driven by a well-designed graphical interface, which
  makes it much easier to learn and use. Remember, the goal your are
  striving for is accurate regression analysis, not learning a new
  proprietary programming language.
- Online help and "tool-tip" text - With context sensitive help and
 "tool-tip" text, the answers to your questions are always close by.
- Straightforward data entry - Data can be entered by typing it into
  a standard spreadsheet interface, by importing it from ASCII files
  created by other applications, or by cutting and pasting it from other
  windows based applications.
- Multi-dimensional regression model capability - DataFit can solve
  regression models with up to 20 independent variables. 
- Built in regression models - there are currently 60 two-dimensional
  and 242 three-dimensional nonlinear regression models built into
  DataFit. The built in nonlinear regression models are commonly used
  in scientific, statistical and engineering applications.
- User defined regression models - If regression models you need are
  not built in to DataFit you can define them yourself. User defined
  regression models can have up to 100 parameters, or variables, and you
  can use whatever variable names you want to use in your model without
  "pre-defining" them. This makes defining your own regression model as
  simple as typing in the equation. You can also assign rule-based
  initial estimates to the models so that the initial estimates don't
  need to be assigned each time you run a regression problem. An
  additional feature is the ability to specify the analytical
  derivatives for user defined models (optional).  
- Robust solver - DataFit utilizes the Levenberg-Marquardt method with
  double precision to perform nonlinear regression. 
- Various solution options - You can 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 one mouse click. The built in models are grouped
  together based on the number of parameters and the general shape of
  their curves. If you continuously solve the same models over and over,
  you can create your own group consisting of the models you choose.
- Automatic solution ranking - As regression models are solved, they are
  sorted automatically according to the goodness of fit criteria you
  specify (Residual Sum of Squares, Correlation Coefficient, DOF
  Adjusted Correlation Coefficient or Standard Error). If you aren't
  an expert and aren't sure which model you should use, DataFit helps
  you make this decision.
- Solution Log - DataFit tracks each step in the regression process and
  reports it to the user in the solution log. If a model fails to solve,
  the solution log contains some diagnostics to help you figure out the
  problem.
- Detailed regression results - DataFit reports the following
  information about each solved regression model automatically without
  additional user action:
    - Number of observations                                            
    - Number of missing observations                                                            
    - Number of nonlinear iterations performed                                          
    - Sum of Residuals                                          
    - Average Residual                                          
    - Residual Sum of Squares                                           
    - Standard Error of the Estimate                                            
    - Coefficient of Multiple Determination (R2)                                                
    - Proportion of Variance Explained                                          
    - Adjusted coefficient of multiple determination (Ra2)                                              
    - Durbin-Watson statistic                                           
    - Coefficient values, Standard Error, t-ratio and Prob(t)
    - Confidence Intervals (68, 90, 95 and 99 percent levels)
    - Variance Analysis (ANOVA) 
    - Data Table, including entered data, calculated data, residual, 
      percent error, minimum residual and maximum residual.
    - Regression model plots
    - Residual Probability plots
    - Residual Scatter plots                    
- Postscript quality plotting capability - 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, etc.  You can also graphically compare the results
  of different models and/or data on the same plot window. Plots can be
  saved along with all of their customization, or copied to the windows
  clipboard for pasting into other applications.
- Data calculator (currently 2D only)- 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 or creating a data table based on an equation
  you type in.
- Automatic source code generation - 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.
- Non-graphical execution - DataFit can be run non-graphically from
  other programs. Simply create a configuration template (either on
  your own or through the interface), save it, and call DataFit from
  your program. You can choose handshaking options, such as DDE
  (Dynamic Data Exchange), progress indicators, and message box
  displays.
- Direct link to the World Wide Web - From the DataFit interface, you
  can connect directly to Oakdale Engineering's home page on the web
  for product updates and technical support. You can also submit bug
  reports or enhancement requests.
