We, the Editors and Publishers of Journal of Statistical Computation and Simulation, are retracting the following article:
Ali A. Ismail & H.M. Aly (2010) Optimal planning of failure-step stress partially accelerated life tests under type-II censoring, Journal of Statistical Computation and Simulation, 80.12, 1335–1348, http://www.tandfonline.com/doi/full/10.1080/00949650903071096.
We are now aware of a substantially similar version of this article, which was concurrently submitted to, and published in International Journal of Mathematical Analysis:
Ali A. Ismail & H.M. Aly (2009) Optimal planning of failure-step stress partially accelerated life tests under type-II censoring, International Journal of Mathematical Analysis, Vol. 3, 2009, no. 31, 1509–1523.
This action constitutes a breach of warranties made by the authors with respect to originality and of our policy on publishing ethics and integrity. We note we received, peer-reviewed, accepted, and published the article in good faith based on these warranties, and censure this action.
