  In this article, a generalized inverse xgamma distribution (GIXGD) has been
introduced as the generalized version of the inverse xgamma distribution. The
proposed model exhibits the pattern of non-monotone hazard rate and belongs to
family of positively skewed models. The explicit expressions of some
distributional properties, such as, moments, inverse moments, conditional
moments, mean deviation, quantile function have been derived. The maximum
likelihood estimation procedure has been used to estimate the unknown model
parameters as well as survival characteristics of GIXGD. The practical
applicability of the proposed model has been illustrated through a survival
data of guinea pigs.
