Abstract |
|
|
| In this study, the extended cosine generalized power Weibull distribution is developed and its statistical properties are studied. Some of the statistical properties studied are the quantile function, moments, moment generating function, incomplete moment, and order statistics. The maximum likelihood and the ordinary least square estimation methods were employed to estimate the parameters. The log extended cosine generalize power Weibull location-scale regression model was developed and its application was demonstrated using the birth weight of babies. The flexibility of the proposed distribution was demonstrated with three data sets. The proposed distribution was compared with its sub-modes and other existing models. The results showed the proposed distribution provided a better fit to the data sets as compared to the other competing distributions. |
