DEXTEROUS ESTIMATION OF POPULATION MEAN IN SURVEY SAMPLING UNDER NON-RESPONSE ERROR

In this scripture, we ponder the problem of efficient estimation of population mean of study variable utilizing information on highly correlated auxiliary variables under the presence of non-response on either of the variables.For this purpose, we suggest, an improved estimator under three different biomat for sale situations of non-response.Under

Abstract The Swampland Distance Conjecture proposes that approaching infinite distances in field space an infinite tower of states becomes exponentially light.We study this conjecture for the complex structure moduli space of Calabi-Yau manifolds.In this context, we uncover significant structure within the proposal by showing that there is a rich s
