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 or ODBC data sources 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.
- Pre-defined regression models - there are currently 74
two-dimensional and 242 three-dimensional nonlinear
regression models pre-defined in DataFit. The pre-defined
nonlinear regression models are commonly used in
scientific, statistical and engineering applications.
- User defined regression models - If regression models you
need are not pre-defined 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 (pre-defined model
groups, or define your own), or all of the models
available with one mouse click. The pre-defined 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
- Presentation 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. Macros can be parameterized which makes batch
processing large numbers of datasets a simple operation.
- 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.
