The derivation of the marginal likelihood based on the original power prior, and its variation, the normalized power prior, introduces a scaling factor C(δ) in the form of a prior predictive distribution with powered likelihood. In this paper, we show that the scaling factor might be inﬁnite for some positive δ with conventionally fms 0.250 ferroxcube
