%description
An ensemble meta-prediction framework to integrate multiple regression
models into a current study. Gu, T., Taylor, J.M.G. and Mukherjee, B.
(2020) <arXiv:2010.09971>. A meta-analysis framework along with two
weighted estimators as the ensemble of empirical Bayes estimators, which
combines the estimates from the different external models. The proposed
framework is flexible and robust in the ways that (i) it is capable of
incorporating external models that use a slightly different set of
covariates; (ii) it is able to identify the most relevant external
information and diminish the influence of information that is less
compatible with the internal data; and (iii) it nicely balances the
bias-variance trade-off while preserving the most efficiency gain. The
proposed estimators are more efficient than the naive analysis of the
internal data and other naive combinations of external estimators.
