At Bureau Waardenburg, a number of our staff are specialised in statistical analysis. Some studies require the use of statistics in the analysis of field data, for example the assessments of trends, analysis of food preference and the analysis of dispersal or habitat preferences. Statistical analysis are carried out using the most recent versions of various statistical software, such as Genstat, Canoco, SPSS and R. We also have a back-up agreement with Biometris, the statistical unit of Wageningen University and Research Centre.
