Abstract: | ![]() A sequence of independent random variables {Zn:n≥ 1} with unknown probability distributions is considered and the problem of estimating their expectations {Mn+1: n≥ 1} is examined. The estimation of Mn+1 is based on a finite set {zk:1≤k≤n}, each zk being an observed value of Zk, 1 ≤k≤n, and also based on the assumption that {Mn:n≥ 1} follows an unknown trend of a specified form. |
