This work explores the use of statistical techniques, namely stratified sampling and cluster analysis, as powerful tools for deriving traffic properties at the flow level. Our results show that the adequate selection of samples leads to significant improvements allowing further important statistical analysis. Although stratified sampling is a well-known technique, the way we classify the data p...
Results from the third nationwide cluster sampling survey on the epidemiology of schistosomiasis in the People's Republic of China, conducted by the Ministry of Health in 2004, are presented.

Results: Coverage for BCG, OPV3, DPT3 & Measles were 92.04%, 85.23%, 83.71% & 82.20% respectively. BCG scar was seen in 83.95% of children out of those who received BCG. The proportions of fully immunized children were 79.55%. Unimmunized children were 4.16%. Dropout rate was 9.05% for BCG-DPT3, 10.69% for BCG-Measles & 7.53% for DPT1-DPT3. Compared to NFHS3 (2005-06) as well as DLHS3 (Gandhina...
Abstract We1 develop Conditional Random Sampling (CRS), a technique particularly suitable for sparse data. In large-scale applications, the data are often highly sparse. CRS combines sketching and sampling in that it converts sketches of the data into conditional random samples online in the estimation stage, with the sample size determined retrospectively. This paper focuses on approximating p...
purpose: the aim of present study was to examining the psychometric properties of the iranian version of short dark triad (sd3) in students. methodology: the study sample consisted of bu-ali sina university students in 2015-2016. 376 students were selected based on multi-stage cluster sampling. to study psychometric characteristics of the scale, dark triad scale was translated with double-trans...
