In this paper, a new generalization of Log-Logistic distribution using Alpha Power transformation is proposed. The new distribution is named as Alpha Power Log-Logistic distribution. A comprehensive account of some of its statistical properties are derived. The maximum likelihood estimation procedure is used to estimate the parameters. The importance and utility of the proposed model are proved empirically using two real life data sets.
