Parameters:

  • n (int) – l in \(E[\overline{y}_{n}^l]\).

  • n1 (int) – times of constant being selected.

  • n2 (int) – times of \(v_{n-1}\) being selected.

  • n3 (int) – times of \(eI_n\) being selected.

  • n4 (int) – times of \(I_n\) being selected.

  • n5 (int) – times of \(I_n^{*}\) being selected.

Returns:

poly with attribute keyfor = (‘e^{-kh}’,’h’,’v_{n-1}’,’k^{-}’,’mu’,’theta’,’sigma_v’,’rho’, ‘sqrt(1-rho^2)’).

Return type:

Poly
