Título

A NEW NADARAJAH-HAGHIGHI GENERALIZATION: SIMULATION AND APPLICATIONS

Resumo

We introduce a new three-parameter model called the logistic Nadarajah-Haghighi distribution. The proposed distribution can produce an unimodal density overcoming a Nadarajah-Haghighi limitation. It is also more flexible than the baseline hazard rate function, allowing constant, increasing, decreasing and upsidedown-bathtub forms. We present the maximum likelihood estimators for the model parameters. A simulation study is carried out and we illustrate the usefulness of the new distribution by means of two applications to real data sets.
