Given any field F, polynomial p : F[X] and natural number d, we have defined Polynomial.hilbertPoly p d : F[X]. If F is of characteristic zero, then for any large enough n : ℕ, PowerSeries.coeff F n (p * (invOneSubPow F d)) equals (hilbertPoly p d).eval (n : F) (see Polynomial.coeff_mul_invOneSubPow_eq_hilbertPoly_eval).

  • The relative value is the weighted sum of the differences with weight given by the inverse of the current value of the statistic.
  • The absolute value is the relative value divided by the total sum of the inverses of the current values (i.e. the weighted average of the differences).

…rty of `Polynomial.hilbertPoly p d` for `p : F[X]` and `d : ℕ`, where `F` is a field. (#19303)

Given any field `F`, polynomial `p : F[X]` and natural number `d`, we have defined `Polynomial.hilbertPoly p d : F[X]`. If `F` is of characteristic zero, then for any large enough `n : ℕ`, `PowerSeries.coeff F n (p * (invOneSubPow F d))` equals `(hilbertPoly p d).eval (n : F)` (see `Polynomial.coeff_mul_invOneSubPow_eq_hilbertPoly_eval`).
