- ajdmom.mdl_2fsv.cmom.moment_comb(n, n1, n2, n3, n4, n5, n6, n7, n8)[source]¶
Moment for this combination of given n1 to n8 with n.
- Parameters:
n (int) – l in \(E[\overline{y}_{n}^l]\).
n1 (int) – times of constant being selected.
n2 (int) – times of \(v_{1,n-1}\) being selected.
n3 (int) – times of \(v_{2,n-1}\) being selected.
n4 (int) – times of \(eI_{1,n}\) being selected.
n5 (int) – times of \(I_{1,n}\) being selected.
n6 (int) – times of \(eI_{2,n}\) being selected.
n7 (int) – times of \(I_{2,n}\) being selected.
n8 (int) – times of \(I_{n}^{*}\) being selected.
