| Description: | Provides an environment for non-linear chi-square and/or least-square fitting and it gives access to the goodness-of-fit, to the covariance matrix and to confidence limits. The fit functions can be archived and maintained in a catalog and the results can be plotted in several ways. Does not auto-attach, so you must manually do a :0:768 ATTACH. | |

| User comments: | Nick Karagiaouroglou 2001-06-21 05:52:09 Fitting data to a specified function is one of the major tasks, when all analytical work simply doesn't work. If for example data of measurements are collected, we may try to find a theoretical function, which represents what we have measured. But sometimes it is difficult/impossible to find such a function with the help of theoretical modelling. Even in such cases, when the data are plotted, one can "see" some kind of dependencies. (Say periodical, exponential and so on, or even a mixture.) These dependencies have by no means to be only the four types, for which the HP49G has a built-in fit procedure. That is where MODA comes in play. This excellent tool allows to fit any data to any specified function. It organizes your functions in families, so that you just type them once and then have them always available. You can also specify error tolerances of the Y-Data (Dependent data) - just another evidence of how professional this tool is. The results are shown in many ways, you can even plot how good the model fits the data. And though of course you can do your jobs interactively with its nice interface, programmatic use is also available. I have used it so many times with so many different data, that now I just consider it to belong to the standand functions of my HP49. It has shown its strength especially with oscillatory fit functions and with data that simply look totally random. In combination with the build-in fourier transform facilities of the HP49, we have a real high end laboratory tool. Since MODA, we can really say, that we can fit anything with the HP49G, except of course for the size of my trousers, which goes up and up as I grow older. ;-) Nick | |
