A New Extension of Power Hazard Distribution with Applications

A new lifetime distribution is suggested using the Sine function by considering power hazard distribution as baseline distribution. Some mathematical and statistical features are discussed. The Maximum likelihood method is used to estimate the parameters for proposed distribution. Three real data sets are examined to analyze the performance of proposed distribution with some other distributions. The new distribution has been shown better fit to the bladder cancer patients’ data and COVID-19 data as compared to some distributions through statistical criterion

Extended Power Hazard Rate Distribution and its Application

A new model four-parameter model called the odd generalized exponential power hazard rate (OGE-PHR) distribution has been introduced. Some statistical properties for OGE-PHR are obtained. The moments, quantile, mode, reliability, and order statistics are discussed. Estimation of parameters, maximum likelihood technique is employed. Two real data sets are discussed with applications.
