- One of the major problems involved in estimating information about economic activity across small domains is too small sample size and incompleteness of data sources. For instance, the distribution of enterprises by target variables tends to be considerably right-skewed, with high variation, high kurtosis and outliers. Therefore, it is not obvious that the implementation of traditional estimation methods meets the desired requirements, such as being free from bias or having competitive variance. Furthermore, the pressure to produce accurate estimates at a low level of aggregation or needs to substantially reduce sample size have increased the importance of exploring the possibilities of applying new, more sophisticated methods of estimation. The aim of the study was to test the usefulness of winsorization methods to estimate economic statistics from the DG1 survey. (original abstract)
