AbstractIn this paper, we propose a flexible extended quadratic hazard rate (EQHR)distribution with increasing, decreasing, bathtub and upside-down bathtubhazard rate function. The EQHR density is arc, right-skewed and symmetricalshaped. This distribution is also obtained from compounding mixturedistributions. Stochastic orderings, descriptive measures on the basis ofquantiles, order statistics and reliability measures are theoreticallyestablished. Characterizations of the EQHR distribution are studied viadifferent techniques. Parameters of the EQHR distribution are estimated using themaximum likelihood method. Goodness of fit of this distribution throughdifferent methods is studied.
