Which versions of Borland Delphi can I use to compile the source code that comes with the Research Edition? |
||
| The source code supplied with FitAll v6.2 Research
Edition can be compiled using Delphi versions 5 to 2010 and TurboDelphi
2006. It also can be compiled with Free Pascal, an open source Pascal compiler, available from www.freepascal.org. |

I have a data acquisition system that collects data from my tests. I would like to use FitAll's analysis engine from within my system to analyze my data. Is this possible? |
||
| FitAll is a stand-alone application and its
analysis engine is not available as a separate library that can be directly
incorported into other applications; HOWEVER, as of version 6.2,
FitAll Research Edition can act as an ActiveX (COM /
Automation) server. This means that other programs, such as data acquisition programs, written in languages like C, Delphi, LabView and Visual Basic can start FitAll, transfer data to FitAll, have FitAll do the regression analysis and retrieve the analysis results from FitAll. A client application, FaClient, that demonstrates how FitAll can be controlled by other programs, is included with FitAll Research Edition. |

Is it possible to have MTR Software develop a custom FitAll Function Library for me? |
||
| Yes. For more information see MTR Software's Consulting Services. | go to top | |
I have successfully created several of my own specialized functions in FitAll and used them to good effect. However, with a couple of my functions, FitAll often, but not always, refuses to show the fit graph. Instead, the fit graph window is completely blank. Sometimes this also happens for the residuals graph. What's going on? |
||
| FitAll creates graphs 'off screen' before
displaying them. If an error is encountered while constructing the graph,
FitAll will abort the operation and may display an empty graph
window or an error message. Sometimes it may close some other windows as well.
This problem is most frequently encountered when the function being evaluated or plotted causes an error such as a 'divide by zero', a 'numeric overflow' or an 'illegal floating point operation' like trying to take the logarithm or square root of a negative number. The 'fix' is to define the function so that 'unusual' or 'special' values of the parameters and variables will not cause such errors. Note: When FitAll is plotting a fit graph, it often sets one of the X-axis limits to zero and evaluates the function at that point -- this could cause the function evaluation to fail and may be the cause of your problem. |
