Abstract:
|
We study Bayesian procedures for high-dimensional sparse regression when unknown nuisance parameters are involved. A mixture of point masses at zero and continuous distributions is used for the prior distribution on sparse regression coefficients, and appropriate prior distributions are used for nuisance parameters to yield the optimal convergence rates of sparse regression coefficients and nuisance parameters. It is shown that the procedure yields strong model selection consistency. A Bernstein-von Mises-type theorem for sparse regression coefficients is also obtained for uncertainty quantification.
