A copula-based joint deficit index for droughts
31 Mar 2010 | Contributor(s): Rao S Govindaraju
Current drought information is based on indices that do not capture the joint behaviors of hydrologic variables. To address this limitation, the potential of copulas in characterizing droughts from multiplevariables is explored in this study. Starting from the standardized index (SI) algorithm, a...
