Variance Estimation Using Auxiliary Information under a One Unit per Stratum Sample Design
I . INTRODUCTION Estimators of the variance of estimators of total or mean using auxil iary information under a one primary sampling unit (PSU) per stratum sample design have been proposed by several authors. Under a one PSU per stratum sample design, the most common variance estimator of the usual estimator of total is the collapsed stratum variance estimator (Cochran (1977)) which has positiv...
متن کاملEffect of Measurement Errors on a Class of Estimators of Population Mean Using Auxiliary Information in Sample Surveys
We consider the problem of estimation the population mean of the study variate Y in presence of measurement errors when information on an auxiliary character X is known. A class of estimators for population means using information on an auxiliary variate X is defined. Expressions for its asymptotic bias and mean square error are obtained. Optimum conditions are obtained for which the mean...
متن کاملinvestigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
Using Auxiliary Information in Statistical Function Estimation
In many practical situations sample sizes are not sufficiently large and estimators based on such samples may not be satisfactory in terms of their variances. At the same time it is not unusual that some auxiliary information about the parameters of interest is available. This paper considers a method of using auxiliary information for improving properties of the estimators based on a current s...
متن کاملProviding a Model for Cost Estimation of Hospital Information System Software Design Using Continuous Decision Tree Algorithm
Introduction: The cost estimation of a hospital information system software refers to estimating the cost and time required to develop the hospital information system software prior to the start of the project, which will continue until the end of production and development of the system. Estimating the cost of software to produce hospital information system is one of the major concerns of proj...
