When looking for properties of the negative exponential distribution, in connection with an X validated question, I came across this nonsensical paper, starting with a truncated and drifted exponential distribution being defined as a negative exponential distribution, including a nonsensical bound a in (1.1), followed by an equally nonsensical characterisation of the distribution, including a theorem with a useless function Φ… Unsurprisingly, the publisher (SCIRP) of the Open Journal of Statistics is part of Beall’s list of potential, possible, or probable] predatory publishers. (List that is now maintained by Scholarly Open Access.)
