In many real life situations the linear cost function does not approximate the actual cost
incurred adequately. The cost of traveling between the units selected in the sample within a …

In this paper, we consider an allocation problem in multivariate surveys with non-linear costs
of enumeration as a problem of non-linear stochastic programming with multiple objective …

In this paper, we consider an allocation problem in multivariate surveys as a convex
programming problem with non-linear objective functions and a single stochastic cost …

The case of nonresponse in multivariate stratified sampling survey was first introduced by
Hansen and Hurwitz in 1946 considering the sampling variances and costs to be …

This paper considers the optimum compromise allocation in multivariate stratified sampling
with non-linear objective function and probabilistic non-linear cost constraint. The …

In this paper, we considered the optimal allocation problem of multiple responses stratified
sample surveys. In the problem, we assume that the following parameters: stratum …

Abstract− In this paper a problem of multivariate stratified sampling for non-linear random
cost with certain probability has been formulated using chance constraint method. Here the …

When more than one characteristics are under study it is not possible for one reason or the
other to use the individual optimum allocation of first stage and second stage sampling units …

This paper extends a multi-choice decision-making approach for a stochastic randomized
response model with two stages in a multivariate stratified sampling problem. In the …

For practical applications of any allocations, integer values of the sample sizes are required.
This could be done by simply rounding off the non-integer sample sizes to the nearest …
