An upper bound for the correlation ratio of records.(English)Zbl 1093.62536

Summary: We obtain an upper bound for a measure of the performance of the least squares predictor of the $$j$$th record of a sequence of continuous i.i.d. random variables as a function of the $$i$$th record. We show also that such bound is attainable, except for location and scale parameters, by exponential distributions.
