Generalized Informational Measures of Space-Time Dependence

F. J. Esquivel, J. M. Angulo, G. Christakos

‘Sysketogram’ and ‘contingogram’ have been proposed as alternative measures to covariance and variogram for quantifying dependence using the information of the two-dimensional distributions corresponding to different pairs of space-time coordinates. These measures can be seen as particular cases of the divergence-based Tsallis mutual information. In this work, among other properties it is found that invariance with respect to nonlinear transformations of the space-time domain holds for any value of the deformation parameter, suggesting the consideration of a general formulation of these informational measures of dependence.

    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.
