  • Abstract
    Necessary and sufficient conditions are established for z−E{xƒx z} to be an increasing function of z. Furthermore, other necessary and sufficient conditions are provided for var {xƒx z} to be an increasing function of z. Log-concavity of the density function and log-concavity of integrals of this function play a central role.
