Abstract
Sector market surveys often require solutions which are not extensively available in literature. In addition to the usual sample bias connected to the sample lists and the information retrieved via questionnaires, one has to deal with the estimation of population variables which are not normally distributed. In this paper we present some proposals on the optimal allocation of the sample units and the use of auxiliary variables in estimation problems which are of interest in the IT sector research.
