7. 5. Survey estimation for highly skewed data

   Author : Forough Karlberg; Chris Skinner; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Extreme values; skewed populations; model-based inference; superpopulation; lognormal distribution; statistik; Statistics;

Traditional methods for outlier treatment will usually compensate for outliers in the sample, thereby avoiding (ii), whereas the small negative bias of (i) will persist. READ MORE
