RT Journal Article T1 The invariant optimal sampling plan in a sequentially planned decision procedure A1 Fenoy Muñoz, María Del Mar AB We define the invariant sequentially planned decision procedure under a group of measurable transformations. By means of a previous reduction of the problem, we obtain the optimal invariant sequentially planned decision procedure that minimizes the risk function. First we find the solution for the horizon with a maximal number of stages, based on the present information; later, the general case is solved but the solution is based on the past information. Finally, we study the possibility of approximating the general case by a sequence of truncated problems with a maximal number of stages, obtaining a solution based on the present informatio PB Taylor & Francis SN 07474946 YR 2017 FD 2017 LK https://hdl.handle.net/20.500.14352/18294 UL https://hdl.handle.net/20.500.14352/18294 LA eng NO Fenoy Muñoz, M.
