Power priors allow principled\nincorporation of historical information while controlling the\ndegree of borrowing through a discounting parameter (Ibrahim\nand Chen (2000) ). This package\nprovides closed-form conjugate representations for both\nunivariate and multivariate normal data using\nNormal-Inverse-Chi-squared and Normal-Inverse-Wishart\ndistributions, eliminating the need for MCMC sampling. The\nconjugate framework builds upon standard Bayesian methods\ndescribed in Gelman et al.
