Query: General proof of a limit related to AR(k) model of Statistics   Computing moments of various parameter estimators related to an
autoregressive model of Statistics, one needs to evaluate several non-trivial
limits. This was done by arXiv:1506.03131 for the case of two, three and four
dimensions; in this article, we present a proof of a fully general formula,
