Table 2:

Summarizing exposure weights in BKMR and the MIM. For BKMR we report posterior inclusion probabilities (PIPs) for each exposure. For MIM, we report the PIP for the entire index via ρ; we also summarize the distribution of weights θ conditional on ρˆ0 (otherwise it is not well defined). Est is the posterior mean standardized to satisfy the constraints; CI is 95% credible interval.
