AbstractIn many contexts it is difficult or impossible to select a simple random sample. For example, the number of units in the finite population, N, may not be known in advance, or it may not be feasible to assign labels to all units in the population and to select an SRS from these labels (e.g., crabs within boxes on a fishing vessel).

Diagonal circular systematic sampling
Model Assisted Statistics and Applications, 2008In this paper a circular version of diagonal systematic sampling has been proposed. The proposed method is compared with the classical circular systematic sampling using natural populations, non-linear populations simulated from well known distributions and a super population model associated with linear trend.

Precision of circular systematic sampling
Journal of Microscopy, 2002SummaryIn design stereology, many estimators require isotropic orientation of a test probe relative to the object in order to attain unbiasedness. In such cases, systematic sampling of orientations becomes imperative on grounds of efficiency and practical applicability.

Systematic sampling is a nonbiased method in recruitment selection process since it is a probability sampling. However, due to slow recruitment, we modified the systematic sampling and evaluate this technique in comparison with the conventional approach of systematic sampling.

A modification on linear systematic sampling
Model Assisted Statistics and Applications, 2013The present paper deals with a modification on the selection of linear systematic sample, consequently the proposed method is called modified linear systematic sampling. The performances of the modified linear systematic sampling are assessed with that of simple random sampling and the linear systematic sampling for certain hypothetical populations as ...

Parameter Estimation in Systematic Sampling
Biometrical Journal, 1993AbstractFirst it is shown that an estimate of the variance of the sample‐mean in systematic sampling from a non‐autocorrelated population with linear trend, which is published in textbooks, isn't a suitable estimate: It is biased and not dependent on the essential parameter, the slope of the linear trend.In section 2 an unbiased estimate of the ...

Systematic Sampling in Image-Synthesis
2006In this paper we investigate systematic sampling in the image- synthesis context. Systematic sampling has been widely used in stereology to improve the efficiency of different probes in experimental design. These designs are theoretically based on estimators of 1-dimensional and 2-dimensional integrals.
