From Mean And Median Income To The Most Adequate Way Of Taking Inequality Into Account, Vladik Kreinovich, Hung T. Nguyen, Rujira Ouncharoen
From Mean And Median Income To The Most Adequate Way Of Taking Inequality Into Account, Vladik Kreinovich, Hung T. Nguyen, Rujira Ouncharoen
Departmental Technical Reports (CS)
How can we compare the incomes of two different countries or regions? At first glance, it is sufficient to compare the mean incomes, but this is known to be not a very adequate comparison: according to this criterion, a very poor country with a few super-rich people may appear to be in good economic shape. A more adequate description of economy is the median income. However, the median is also not always fully adequate: e.g., raising the income of very poor people clearly improves the overall economy but does not change the median. In this paper, we use known techniques …
How To Estimate Relative Spatial Resolution Of Different Maps Or Images Of The Same Area?, Christian Servin, A A. Velasco, Vladik Kreinovich
How To Estimate Relative Spatial Resolution Of Different Maps Or Images Of The Same Area?, Christian Servin, A A. Velasco, Vladik Kreinovich
Departmental Technical Reports (CS)
In this paper, we describe how to estimate relative spatial resolution of different maps or images of the same area under uncertainty. We consider probabilistic and fuzzy approaches and we show that both approaches lead to the same estimates -- which makes us more confident that this joint result is reasonable.
