    Characterization results based on a functional derivative approach. (English)
    0 references
    A unified approach based on functional derivatives is given for characterizing probability distributions via conditional expectations. Among the characterization results that have been dealt with here are those that have links with certain results met in [\textit{S. Kotz} and \textit{D. N. Shanbhag}, Adv. Appl. Probab. 12, 903--921 (1980; Zbl 0454.62085)]. Some related results in differential calculus and statistical inference are also discussed.
