Konstruktion eines sequentiellen Konfidenzsehatverfahrens mit vorgegebener Intervallange fur den Erwartungswert exponentialverteilter Stichprobenwerte

摘要

When the sample variables Xiare exponentially distributed with mean EXii=?, then, for ?, a fixed-width confidence estimation observing the confidence level for all values of ?0 is stated. It can be seen that the asymptotic effectiveness of the procedure obtained is no worse than that achieved by a stopping rule derived from asymptotic theory, whose disadvantages are, however, avoided (the cover probability failing very below the confidence level for finite values of ?)
