Comment on 'Generalized Heisenberg algebra coherent states for power-law   potentials'
  We argue that the statistical features of generalized coherent states for power-law potentials based on Heisenberg algebra, presented in a recent paper by Berrada et al (Phys. Lett. A, 375, 298 (2011)) are incorrect.
