In this paper, we introduce a new family of continuous distributions called the beta transmuted Dagum distribution which extends the beta and transmuted family. The density function, hazard function, shape of the density and hazard functions, moments, moment generating function, quantiles and stress-strength of the beta transmuted Dagum distribution(BTD) are provided and discussed in detail. We discuss the maximum likelihood estimation of the model parameters. We assess the performance of the maximum likelihood estimators in terms of biases, standard errors, and mean square of errors by means of simulation studies. The usefulness of the new model is illustrated through an application to survival dataset.
