‘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.
