      note         = {There are many areas in the research with neutrons where
                      model ttingand parameter estimation play a great role.
                      Physical laws that are alreadyexplored, oer models that
                      depend on dierent parameters. Those models canbe used for
                      simulating an experiment, for example by specifying the
                      parame-ters, or those models can be used for estimating the
                      parameters by tting themodel to experimental data.In this
                      work, two sub-areas of neutron research, each with a specic
                      case ofmodel tting and parameter estimation, are examined in
                      more detail.On the one hand, the calculation of the
                      parameter uncertainties in the Levenberg-Marquardt algorithm
                      is considered. The algorithm is used by the softwareSteca to
                      t the data from neutron diraction to a model.Furthermore,
                      the Dierential Evolution Algorithm is looked upon, which
                      isconsidered to be added to the software BornAgain , a
                      software for simulatingand tting X-ray and neutron
                      reectometry, as a further algorithm for pa-rameter
                      estimation. As BornAgain is programmed in C ++ , I discussed
                      thepossibility of accessing the Python implementation of the
                      Dierential Evolu-tion algorithm.; Bachelorarbeit, Hochschule
