Motivation for ROOT

The Comparison of measurements to theoretical models is one of the standard tasks in experimental physics. In the most simple case, a “model” is just a function providing predictions of measured data.

the model usally depends on parameters. Using this parameters theretical model....... ..In the first step, the visualisation of the data is needed. Next, some manipulations typically have to be applied, e.g. corrections or parameter transformations. Quite often, these manipulations are complex, and a powerful library of mathematical functions and procedures should be provided - think for example of an integral or peak-search or a Fourier transformation applied to an input spectrum to obtain the actual measurement described by the model.

A specialty of experimental physics are the inevitable uncertainties affecting each measurement, which have to be included in the visualisation tools. In subsequent analyses, the statistical nature of the errors must be handled properly. In the last step, measurements are compared to models, and free model parameters need to be determined in the process.
