the claims' randomness, namely, one part accounting for claims' frequency and the other
part for claims' severity. For a Negative Binomial number of claims, we focused on the
modelling of claim severities using a hybrid structure. While Weibull distribution is suggested
for constructing smaller-sized claims, Pareto severities employed by (1) were applied to
model large ones. A generalised function for the BM premium rates is then derived. Results …
