Advances in estimation by the item sum technique in two move successive sampling

Priyanka, Kumari; Trisandhya, Pidugu - In: Statistics in transition : an international journal of … 24 (2023) 4, pp. 123-138

The present article proposes an estimator using the Item Sum Technique (IST) for the estimation of dynamic sensitive population mean using non-sensitive auxiliary information in the two-move successive sampling. Properties of the proposed IST estimator have been analysed. Possible allocation...

Missing data estimation based on the chaining technique in survey sampling

Thakur, Narendra Singh; Shukla, Diwakar - In: Statistics in Transition new series (SiTns) 23 (2022) 4, pp. 91-111

Sample surveys are often affected by missing observations and non-response caused by the respondents' refusal or unwillingness to provide the requested information or due to their memory failure. In order to substitute the missing data, a procedure called imputation is applied, which uses the...

Optimal allocation for equal probability two-stage design

Molefe, Wilford - In: Statistics in Transition new series (SiTns) 23 (2022) 4, pp. 129-148

This paper develops optimal designs when it is not feasible for every cluster to be represented in a sample as in stratified design, by assuming equal probability two-stage sampling where clusters are small areas. The paper develops allocation methods for two-stage sample surveys where...

MSE Performance of the Weighted Average Estimators Consisting of Shrinkage Estimators

Namba, Akio; Ohtani, Kazuhiro - Faculty of Economics, Kobe University - 2015

among three estimators; the Stein-rule (SR), minimum mean squared error (MMSE) and the adjusted minimum mean squared error … (AMMSE) estimators. We derive the formula for the mean squared error (MSE) of the proposed estimators. It is shown by … numerical evaluations that one of the proposed estimators has smaller mean squared error (MSE) than the positive-part Stein …
