On random non-response in double sampling with difference estimator

Abstract

The present paper considers t h e comparison o f t h e double sampling d i f f e r e n c e e s t i m a t o r given i n Singh and Singh (1979) f o r random non-response and t h e simple random sample mean w i t h respect t o these concepts. The empirical study shows t h a t t h e r e l a t i v e e f f i c i e n c y and a l s o t h e r e l a t i v e non-response robustness o f t h e simple sample mean ( w i t h respect t o the d i f f e r e n c e estimator) are decreasing f u n c t i o n s o f t h e r a t e o f random nonresponse.
