An exponential power life-testing distribution

An extreme-value type life-testing distribution is studied which has the property that the hazard function say assume a U-shaped form. Also the hazard function is exponentially increasing on the right. Some general properties of least squares type estimators are discussed for the case of location-scale parameter distributions, and these estimators are applied to the proposed model. Properties of the estimators are studied by Monta Carlo simulation, and procedures for interval estimation and tests of hypotheses for the parameters and reliability are provided. A numerical example is also considered.
