ajdmom.mdl_1fsv.cov.ve_IEII_vn¶

ajdmom.mdl_1fsv.cov.ve_IEII_vn(n2, n3, n4, n5)[source]¶

Compute \(v_n^{n_2}e^{-n_3k(n+1)h} IEII\) and expand \(v_n\)

Parameters:

n2 (int) – \(n_2\) in above equation.
n3 (int) – \(n_3\) in \(IEII\) which is \(E[IE_{n+1}^{n_3}I_{n+1}^{n_4}I_{n+1}^{*n_5}|v_n]\).
n4 (int) – \(n_4\) in \(IEII\).
n5 (int) – \(n_5\) in \(IEII\).

Returns:

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

Return type:

Poly
