ajdmom.mdl_2fsvj.mom.dpoly(poly, wrt)[source]

Partial derivative of moment w.r.t. parameter wrt

Parameters:

  • poly (Poly) – poly with attribute keyfor = (‘(n_1m*k1+n_2m*k2)^{-i_m},…,(n_11*k1+n_21*k2)^{-i_1}’, ‘e^{-(n1*k1+n2*k2)h}’,’h’,’mu’, ‘theta1’,’sigma_v1’,’theta2’,’sigma_v2’,’lambda’,’mu_j’,’sigma_j’).

  • wrt (str) – with respect to.

Returns:
