Abstract
:
A new odds exponential-Pareto IV distribution is defined and investigated.Also, log exponential-Pareto and log odds exponential-Pareto IV distributions are introduced.Some of their properties are derived.Moreover, two new location-scale regression models are constructed;one based on the log exponential-Pareto and the other based on the log odds exponential-Pareto IV distributions.The maximum likelihood method is applied to estimate the parameters of the odds exponential-Pareto IV distribution.Also, the parameters of the proposed regression models are estimated using two different methods for censored data. First, the maximum likelihood estimators are obtained along with their asymptotic variance covariance matrices and confidence intervals.Additionally, jackknife method is considered as another method to estimate the unknown parameters.The sensitivity analysis are applied to detect the possible influential observations.Also, martingale and deviance residuals are explored to assess the adequacy of the proposed model and to detect outliers.The efficiency of maximum likelihood estimators for the parameters of odds exponential-Pareto IV distribution is investigated using some Monte Carlo simulation studies.Also,the performance of the maximum likelihood estimate is compared with the jackknife estimate through some Monte Carlo simulation studies for the proposed regression models.The simulation results showed that the jackknife estimates are more efficient than the maximum likelihood estimates based on average of standard error.The martingale and deviance residuals properties are computed and the empirical distributions are plotted.Finally,the real-data sets are analyzed under the odds exponential-Pareto IV distribution to show the potentiality of this new distribution.Also, the flexibility of the regression models are illustrated by mean of some real-life applications.The results demonstrated the superior performance of the proposed models.
