The Renyi type of this has a special case where alpha equals one which produces the Kullback-Leibler divergence and the Shannon form of it.  
The Renyi type of this has a special case where alpha equals one which produces the Kullback-Leibler divergence and the Shannon form of it.  The Tsallis type of it is a generalization of the more common Boltzmann-Gibbs type, and it shares the same units with Boltzmann's Constant.  One representation of it is as time's arrow.  It approaches a minimum as the temperature nears absolute zero, while it is slated to increase over time by the Second Law of Thermodynamics.  For 10 points, identify this measure of randomness of elements in a system.
