The behaviour of Benn’s p exponent in a SD-classified model population normally distributed in the body weight and height

Boris Neruda

Abstract


In this short communication the influence of classifying a model population into 5 different weight-height classes upon the exponent p of Benn's index (W/Hp) was studied. Such a classification stratifies data into subspecies with different physics. The Benn's index is known to be gender and also population specific, where figures for males range between 1.65 and 1.83 [2]. Therefore, it was hoped to discover a similar effect of such a classification on the expression of exponent p and it was expected to find some difference in exponent p at least between not neighbouring classes. This, however, was not the case, probably because the underlying population was constructed under strict assumptions, which do not prevail in biased ordinary populations.
