The issue of the sacrifice of Abrahim’s son remain an important bone of contention among the followers of Abrahamic religions. The Jews and Christians believe that it is Ishaq while among the Muslims some opine in favour of Ismail while favours Ishaq. To a common man it seems to be not an important issue whether it is Ismail or Ishaq but when its implications are taken into account then it is of great value to Muslims, Jews and Christians that who was sacrificed? Ismail or Ishaq. In the following pages an effort is made to look the issue in the light of some contemporary researches conducted in the Indo-Pak Subcontinent in the first half of the 20th century. Different positions on the issue are evaluated with the Quran and other holy scriptures and in the contemporary western scholarships.
Most of the data sets belonging to the real world contain observations at the extremes that might not be in conformity with the remaining data set. These extreme observations known to be outliers might have positive or negative effect on the data analysis like regression estimates, forecasting and ANOVA etc. Outliers are powerful tools to identify the most interesting events of the world in cross sectional data and historically important events can be picked by detecting outliers in time series data sets. Numerous outlier detection techniques have been proposed in the literature. This study provides a survey of these techniques and their properties. Most of these techniques work well under the assumption that data come from a symmetric distribution and these techniques fail to work in skewed distributions. Because of this limitation, Hubert and Vandervieren (2008) proposed a technique for outlier‟s detection in skewed data sets. Our thesis presents a new technique to measure robust skewness (SSS) and a new outlier detection technique (SSSBB) for skewed data distributions. The study shows that the proposed technique measures skewness more accurately than existing techniques and the proposed technique for outlier‟s detections works better than Hubert‟s technique on a class of theoretically skewed and symmetric distributions. The study also compares the technique with other established outlier detection techniques in the literature. This study uses simulation technique for computer generated distributions and some real data sets for comparison purposes. The study also analyzes real life data sets and compares the baby birth weight data and stock returns, both of which are known to be skewed. These results will help us in making a choice of appropriate outlier detection technique for skewed data sets for different sample sizes which might be helpful in identifying underweight babies.
