[HTML][HTML] Log-concavity and strong log-concavity: a review

A Saumard, JA Wellner - Statistics surveys, 2014 - ncbi.nlm.nih.gov
We review and formulate results concerning log-concavity and strong-log-concavity in both
discrete and continuous settings. We show how preservation of log-concavity and strongly …
