Torsion balance measurements in Hungary were checked by least-squares collocation. The methodology was the so-called "leave-one-out" prediction of horizontal gravity gradients. The method was succesfully tested on a selected subset of 700 torsion balance measurements and only three possible outliers has been detected. These results are promising in view of a planned new Hungarian geoid determination.
