Most estimators in probability proportional to size (PPS) with replacement (WR) sampling design are defined for positively correlated variables. The literature on estimators involving negatively correlated variates is underdeveloped. This study utilized the law of inverse proportion to derive...

In this paper, we studied estimators based on an interval shrinkage with equal weights point shrinkage estimators for all individual target points ¯θ ∈ (θ0,θ1) for exponentially distributed observations in the presence of outliers drawn from a uniform distribution. Estimators obtained from...
