A New Lifetime Parametric Model for the Survival and Relief Times with Copulas and Properties

In this article, we introduce a new generalization of the Exponentiated Exponential distribution. Various structural mathematical properties are derived. Numerical analysis for mean, variance, skewness and kurtosis dispersion index performed. The density can be right skewed symmetric with "unimodal" "bimodal" shapes. hazard function "constant", "monotonically decreasing", " monotonically increasing", "increasing-constant”, “upside-down-constant", "decreasing-constant". Many bivariate multivariate type model have been also We assess performance maximum likelihood method graphically via biases mean squared errors. applicability life distribution is illustrated by means two real data sets.
