Testing a large number of multinomial two-sample problems with application in digital elevation models
M. V. Alba Fernández, M. D. Jiménez Gamero
A Digital Elevation Model (DEM) is a bare earth elevation model representing the surface of the Earth. To compare two DEMs, a multivariate and spatialized perspective is proposed. This way, to determine whether two DEMs can be considered as similar: (i) a spatialization (natural or artificial) of the study area is needed, (ii) from each spatial unit, the same categorized variable is derived from each DEM for further comparison, and (iii) the similarity between two DEMs will be equivalent to test a large number of the equalities of categorized variables. A test statistic based on the Euclidean distance between the estimated proportions in each pair of populations is designed. The null distribution of the test statistic is unknown and its asymptotic null distribution is derived. A simulation study is carried out to evaluate the behaviour of the proposal in a wide range of scenarios. Finally, an application to two DEM datasets from the same zone (Allo, Navarra, Spain) is detailed.

Visit Alhambra
Tomorrow, Thursday, we will visit the Alhambra. 1. At 7:00 p.m., buses will start leaving from the door of the Hotel Granada Center (in front of the door of the Faculty of Sciences) 2. Upon arrival, groups with guides will be organized. 3. There will be groups in English language. These groups will wait at the destination until the arrival of all buses. 4. After the visit to the Alhambra we will walk to the Carmen de los Mártires to have a cocktail. 5. On the way back, we can go back by bus, which will leave from the same place where they left us at the Alhambra. 6. Although the way to the Alhambra by bus seems long, it really is close to the city. We invite you, whoever wishes, to go down for a pleasant walk. 7. Do not forget to take your Alhambra ticket and your identity card or passport. The document must be the same whose number matches the ticket number you have.
