In this article we propose a two-parameter power Garima distribution which includes Garima distribution as particular case. Its statistical properties including behavior of its probability density function for varying values of parameters, moments, hazard rate function and mean residual life function has been discussed. The estimation of the parameters of the distribution has been discussed using maximum likelihood estimation. Applications of the distribution have been investigated using real lifetime datasets from engineering and medical science.

Keywords:Garima distribution; Moments; Hazard rate function; Mean residual life function; Maximum likelihood estimation; Applications
