The same table shows also the same analysis with respect to the Jarque-Bera test. The value of alpha for this test was set to 5%. The difficulty to transform the data into normally distributed samples derives from the original distribution of run performances which tend towards zero within the interval [0,1]. Figure 12 presents a boxplot graph providing a more detailed analysis of the above mentioned phenomenon for the bilingual task with Bulgarian target collection. As can be seen, the distribution of the average precision for the different experiments is skewed, and this helps to explain the deviation from the normality.
