Query: New probability distributions in astrophysics: II. The generalized and
  double truncated Lindley   The statistical parameters of five generalizations of the Lindley
distribution, such as the average, variance and moments, are reviewed. A new
double truncated Lindley distribution with three parameters is derived. The new
distributions are applied to model the initial mass function for stars.
