karbasian M, Ibrahim Z. Estimation of Parameters of the Power-Law-Non-Homogenous Poisson Process in the Case of Exact Failures Data. IJIEPR. 2010; 21 (2) :105-110 URL: http://ijiepr.iust.ac.ir/article-1-199-en.html
This expository article shows how the maximum likelihood estimation method and the Newton-Raphson algorithm can be used to estimate the parameters of the power-law Poisson process model used to analyze data from repairable systems .
