Abstract :
A new generalized distribution called the gamma odd power generalized
Weibull-G family of distributions is developed and studied. Some special models of
the new family of distribution are explored. Statistical properties of the new family of
distributions including the quantile function, ordinary and incomplete moments, probability
weighted moments, stochastic ordering, distribution of the order statistics, and
Rényi entropy are presented. The maximum likelihood method is used for estimating
model parameters, and Monte Carlo simulation is conducted to examine the performance
of the model. The flexibility of the new family of distributions is demonstrated
by means of two applications to real data sets.
