Using a microbased superpopulation approach some aspects of optimal prediction of aggregated AR(1) processes are studied.

The question of minimizing the bias due to the survey sampling error when estimating the autocorrelation function of aggregated AR(1) processes is studied.

Analysts using data from official statistical authorities often neglect the fact that data frequently are collected using sample surveys. In this paper the impact of sampling error on the estimation of the autocovariance and the autocorrelation function is studied under a micro based...

Analysts using data from official statistical authorities often neglect the fact that data frequently is collected using sample surveys. We study the impact of sampling error on the estimation of the autocorrelation function for a population total under a microbased superpopulation time series...

In Cassel and Lundquist (1990) the existence of sampling bias in estimating autocorrelation functions was discussed under a superpopulation model. One restriction of that model was that the time series model should not exhibit trend. In this paper we relax that restriction. The bias of a...

An estimator of population parameters for cross sectional analysis is suggested. The estimator is basically the generalised regression estimator (TGR) but with an adjustment derived from optimal predictors of AR(1)-series. The P- properties of the estimator are studied and the efficiency of the...

The present article examines the linear estimation of a finite population mean, under a regression superpopulation model with unknown parameters and correlated residuals. Asymptotic design unbiasedness and weak robustness are desirable properties of the estimators when the model is misspecified....

It will be discussed if the confidence in the results of the production of economic and social data will be justified. Probability based conclusions are possible concerning the sampling error. In order to quantify the non-sampling error an accuracy check is necessary which causes practical...

Beyer, Doornik and Hendry (2000, 2001) show analytically that three out of four aggregation methods yield problematic results when exchange rate shifts induce relative-price changes between individual countries and found the least problematic method to be the variable weight method of growth...
