The purpose of this paper is to introduce a new family of Marshall–Olkin extended generalized
linear exponential distribution. This new family has the advantage of being capable
of modeling various shapes of aging and failure criteria. The proposed family includes as
special cases several Marshall–Olkin extended distributions studied in the literature such
as exponential, Rayleigh, linear failure rate and Weibull, among others. Some statistical
and reliability properties of the new family are discussed and an explicit expressions for
the quantiles are derived. The method of the maximum likelihood estimation is used to
estimate the unknown parameters. In addition, the asymptotic confidence intervals for the
parameters are derived from the Fisher information matrix. Finally, the obtained results are
validated using some real data sets and it is shown that the new family provides a better
fit than some other known distributions.
