Abstract |
|
|
| The exponentiated -parent distribution is a generalization of the standard parent distribution. [7] introduced a simple generalization
to weibull distribution namely the exponentiated weibull distribution. The new distribution was applied to analyzing bathtub
failure rates lifetime data. In this paper, we consider the standard exponentiated inverted weibull distribution (EIW) that generalizes the
standard inverted weibull distribution (IW), the new distribution has two shape parameters. The moments, median, survival function,
hazard function, maximum likelihood estimators, least-squares estimators, fisher information matrix and asymptotic confidence intervals
have been discussed. A real data set is analyzed and it is observed that the (EIW) distribution can provide a better fitting than (IW)
distribution.
