Opis:: A class of linear regression models has been proposed for the estimation of population mean and total when information regarding auxiliary variate is available in survey sampling using regression method of estimation by introducing a new auxiliary variable z, which may also be a function of the auxiliary variable x. The proposed model leads to reduction in mean squared error as compared to ordinary regression method of estimation. The improvement has been demonstrated over ordinary regression estimator and also on ratio estimator with the help of an empirical example.

Tytuł:: On Efficient Difference Type Estimators
Autorzy:: Swain, A. K. P. C.
Powiązania:: https://bibliotekanauki.pl/articles/465693.pdf
Data publikacji:: 2010
Wydawca:: Główny Urząd Statystyczny
Tematy:: Difference type
Ratio type and Regression type estimators
Efficiencies of estimators
Auxiliary information
Simple random sampling without replacement
Opis:: This paper considers a more efficient difference type estimator in a finite population set-up. Ratio type and regression type estimators are derived as special cases. Further efficiencies of these estimators are compared with classical ratio and regression estimators. Numerical illustrations are provided to compare efficiencies of different competitive estimators.

Tytuł:: On Classes of Modified Ratio Type And Regression-Cum-Ratio Type Estimators in Sample Surveys Using Two Auxiliary Variables
Autorzy:: Swain, A. K. P. C.
Powiązania:: https://bibliotekanauki.pl/articles/465714.pdf
Data publikacji:: 2012

Tematy:: ratio type estimators regression-cum-ratio type estimators simple random sampling

Opis:: In this paper generalized classes of modified ratio type and regression-cum-ratio type estimators of the finite population mean of the study variable are suggested in the presence of two auxiliary variables in simple random sampling without replacement when the population means of the auxiliary variables are known in advance. Some special cases of the generalized estimators are compared with respect to their biases and efficiencies both theoretically and with the help of some natural populations.
