DOI: 10.1007/s11222-017-9792-0
Abstract: We propose methods to construct a biased linear estimator for linear regression which optimizes the relative mean squared error (MSE). Although there have been proposed biased estimators which are shown to have smaller MSE than… read more here.

DOI: 10.1016/j.jksus.2018.12.005
Abstract: Abstract In this article, we propose a general family of exponential-type estimators for enhanced estimation of population mean in simple random sampling. These estimators are based on the available parameters of the auxiliary variable such… read more here.

DOI: 10.1103/physreve.106.l052602
Abstract: The active Brownian particle (ABP) model is widely used to describe the dynamics of active matter systems, such as Janus microswimmers. In particular, the analytical expression for an ABP's mean-squared displacement (MSD) is useful as… read more here.

DOI: 10.1177/0013164420926231
Abstract: We examine the accuracy of p values obtained using the asymptotic mean and variance (MV) correction to the distribution of the sample standardized root mean squared residual (SRMR) proposed by Maydeu-Olivares to assess the exact… read more here.
