Abstract: There is an extensive literature on fixed-size confidence regions for the regression parameters in a linear model with p regressors, attaining a prescribed coverage probability when p is fixed and the size d approaches 0. Motivated by recent developments in regression modeling in response to applications for which p is considerably larger than the sample size, we develop herein a more versatile sequential methodology for fixed-size confidence regions that can handle the case p = p(d) → ∞ as d → 0.
