Following improvements should be checked:
A. Find fit parameter in user supplied fit function automatically - DONE
Currently the fit parameter has to be given by the user which is more work than necessary. We should check if we can get this information from the parser.
B. Improve output of results.
* use tables to improve visibility - DONE
* calculate t, p- value and conf. interval of parameter - DONE
* calculate p value for chi-square test - CHECK
* calculate p value for F test - TODO
