- ajdmom.mdl_2fsv.cov.moment_inner_comb(l1, m1, m2, m3, m4, m5, m6, m7, m8, poly_eIv)[source]¶
Moment for this inner combination in expansion of \(y_n^{l_1}\)
- Parameters:
l1 (int) – l1 in \(y_n^{l_1}\).
m1 (int) – times of constant being selected.
m2 (int) – times of \(v_{1,n-1}\) being selected.
m3 (int) – times of \(v_{2,n-1}\) being selected.
m4 (int) – times of \(eI_{1,n}\) being selected.
m5 (int) – times of \(I_{1,n}\) being selected.
m6 (int) – times of \(eI_{2,n}\) being selected.
m7 (int) – times of \(I_{2,n}\) being selected.
m8 (int) – times of \(I_{n}^{*}\) being selected.
poly_eIv (Poly) – poly with attribute
