New Ratio Estimators in Simple Random Sampling Using (K) Factor [PDF]
المجلة العراقية للعلوم الاحصائية, 2010 In this research we find alternative ratio estimators to the suggested estimators for [Sesodia and Dwivedi] , [Singh and Kakran] and [Upadhyaya and Singh] , in simple random sampling by using (K) factor.

Estimators in simple random sampling: Searls approach [PDF]
Songklanakarin Journal of Science and Technology (SJST), 2013 This paper investigates four new estimators in simple random sampling: biased sample mean, ratio estimator and two linear regression estimators, using known coefficients of variation of the study variable and auxiliary variable. The properties of the new

Relaxation of monotone coupling conditions: Poisson approximation and beyond [PDF]
, 2017 It is well-known that assumptions of monotonicity in size-bias couplings may be used to prove simple, yet powerful, Poisson approximation results. Here we show how these assumptions may be relaxed, establishing explicit Poisson approximation bounds ...

Optimal neutrosophic framework for population mean estimation under simple random sampling [PDF]
Neutrosophic Sets and SystemsWhen conducting survey sampling, precise population mean estimation is essential, particularly when additional indeterminate data is available. The intrinsic ambiguity and uncertainty in the study and auxiliary variables are handled by using neutrosophic

Uniform Sampling for Matrix Approximation [PDF]
, 2014 Random sampling has become a critical tool in solving massive matrix problems. For linear regression, a small, manageable set of data rows can be randomly selected to approximate a tall, skinny data matrix, improving processing time significantly.
