Kernel Density Estimation of metal axes from Denmark, England, Wales and the Netherlands ...

As part of a Master's thesis, Kernel Density Estimations (KDEs) using likelihood cross-validation bandwidth were calculated for metal axes found by private metal detectorists. The data derives from England and Wales (Portable Antiquities Scheme), Denmark (Digitale Metaldetektorfund) and the Netherlands (Portable Antiquities Scheme). Calculations were performed with the 'density' function in R. ...
