A robust unbiased dual to product estimator for population mean through modified maximum likelihood in simple random sampling
In simple random sampling setting, the ratio estimator is more efficient than the mean of a simple random sampling without replacement (SRSWOR) if $ \rho_{yx} > \frac{1}{2}\frac{{C_{x} }}{{C_{y} }} $, provided R > 0, which is usually the case. This shows that if auxiliary information is such t...
