La Elasticidad; Una nueva herramienta para caracterizar distribuciones de probabilidad

The elasticity of the distribution function of a random variable is a concept just recently introduced instatistics from economics. This work shows, in both the continuous and discrete case, how the probability distribution ofthe random variable could be characterized from it and illustrates this through several examples. We hope analysts foundin the elasticity a new tool for understanding the situations of risk and uncertainty and that, moreover, this makespossible to merge new random models, hardly imaginable or justifiable otherwise.
