So we create a class whose job it is to maintain a singleton for our factory class, and a reference to the algorithm that actually implements our method. This class provides the old interface we have from above, but defers to a separate (and new and improved!) algorithm engine: public c...
The explanatory variables of RH, CBC, CBC / CPM1, CPM1/CPM2.5 and CPM2.5/CPM10 were proposed by using the combination of multivariate recursion and VIF method, among them RH and CBC exerted considerable effects on Gf, the adjusted coefficients of dete...
The recursion depth is $O(\log_p n)$, and therefore the complete asymptotic behavior of the algorithm is $O(p \log_p n)$.Notice, if you precompute the factorials $0!,~ 1!,~ 2!,~ \dots,~ (p-1)!$ modulo $p$, then the complexity will just be $O(\log_p n)$....
