Sequential estimation of exponential lacation parameter using an asymmetric loss function

For a two-parameter negative exponential population with both parameters unknown, the bounded risk sequential estimation problem of the location parameter is considered under an asymmetric linex loss funmction. Asymptotic second-order expansion of the risk function is derived for a general class of stopping variables. Some examples are include involving purely scquential and accelerated sequential sampling methodologies. A Monte-Carlo study is carried out to support the asymptotic results and to compare the performance of the different sampling methodologies.
