An exponential-inverse-exponential {Weibull} regression failure model is introduced. Some of its properties like density function, survival and hazard function are derived. Maximum likelihood estimates the parameters new from censored data obtained. To assess local influence diagnostic(s) on parameter estimates, appropriate matrices Also, global used to detect influential observations. Martinga...

We define a new quantile regression model based on reparameterized exponentiated odd log-logistic Weibull distribution, and obtain some of its structural properties. It includes as sub-models known models that can be utilized in many areas. The maximum likelihood method is adopted to estimate the parameters, several simulations are performed study finite sample properties estimators. applicabil...

Background and aims: Although accident is the secondary cause of mortality in Iran, information on the occurrence and mortality are not wholly understood. The study aimed to explore seasonal occurrence and mortality pattern of traffic accidents in Isfahan population, Iran. Methods: This study was a cross-sectional. The data on traffic accidents of Isfahan Province was extracted from the Minist...
