      Strengthened Chernoff-type variance bounds 

      Afendras, Georgios; Papadatos, Nickos (2014)
      Let X be an absolutely continuous random variable from the integrated Pearson family and assume that X has finite moments of any order. Using some properties of the associated orthonormal polynomial system, we provide a ...
