Figure 2: as a function of σ_{a0} under the normalized power prior
(NPP) when D under the normalized power prior (NPP) when D = D_{0}. Current
data sample sizes are (a) n = 1, (b) n = 2, (c) n = 10, and (d) n = 100. Each
plot presents trends when historical sample sizes are inflated by factors of
1 (solid), 2 (dashed) and 5 (dotted). The fi gures suggest that, unlike the IC
power prior, the NPP is relatively invariant to changes in n and n_{0} when the
data are identical. |
