Abstract

In the present paper, moments and moments based characteristics including expressions for coefficient of variation, skewness, kurtosis and index of dispersion of the three-parameter generalized Lindley distribution (GLD) introduced by Zakerzadeh and Dolati have been derived and discussed. The expressions for the hazard rate function and the mean residual life function of the distribution have been obtained. The applications and goodness of fit of the GLD have been discussed with several lifetime data sets from biomedical science and engineering and the fit has been compared with the three –parameter generalized gamma distribution (GGD).
