Improvement in Estimating Population Mean using Two Auxiliary Variables in Two-Phase Sampling
Rajesh Singh, Pankaj Chauhan, Nirmala Sawan +1
This study proposes improved chain-ratio type estimator for estimating population mean using some known values of population parameter(s) of the second auxiliary character. The pro…
A Note on Testing of Hypothesis
Rajesh Singh, Jayant Singh, Florentin Smarandache
In this paper, a problem of testing is discussed when the samples have been drawn from the normal distribution. The study of hypothesis testing is also extended to Baye's set up.
A General Family of Estimators for Estimating Population Mean Using Known Value of Some Population Parameter(s)
M. Khoshnevisan, Rajesh Singh, Pankaj Chauhan +2
A general family of estimators for estimating the population mean of the variable under study, which make use of known value of certain population parameter(s), is proposed. Under…
Econometric Analysis on Efficiency of Estimator
M. Khoshnevisan, F. Kaymram, Housila P. Singh +2
This paper investigates the efficiency of an alternative to ratio estimator under the super population model with uncorrelated errors and a gamma-distributed auxiliary variable. Co…
