Pearson's system of frequency curves whose left boundary and first three momentsare known
Leichtweiss-Institut für Wasserban der Technischen Universität Braunschweig
For a known left boundary it is possible to compute a kurtosis ß23 by use ofthe known mean, standard deviation and skewness. We show thus derived densities for types I, III, V and VI of the Pearson system and indicate a way to use published tables of standardized percentage points.
