STATISTICAL PROPERTIES AND APPLICATION OF THE EXPONENTIAL DAGUM LOG-LOGISTIC DISTRIBUTION

In this paper, we propose a new distribution from the T-R{Y} family of distributions called the Exponential Dagum Log-logistic (EXDAL) distribution. The statistical properties of the proposed distribution are carefully discussed. The maximum likelihood method of parameter estimation is employed for the estimates of the parameters of the proposed distribution. The flexibility of the proposed distribution is demonstrated using a real life dataset. Result from the application of the proposed distribution reveals that it performs better than the Dagum and Log Logistics distribution in fitting real life dataset.
