Thank Prof. Pfeifer for your answers.
But I have another question.
Which means the collinearity of these parameters.
alpha is collinear w.r.t. all other params!
eta is collinear w.r.t. all other params!
gammac is collinear w.r.t. all other params!
c_y is collinear w.r.t. all other params!
phi is collinear w.r.t. all other params!
sigma is collinear w.r.t. all other params!
vphi is collinear w.r.t. all other params!
t_y is collinear w.r.t. all other params!
mu_c is collinear w.r.t. all other params!
mu_h is collinear w.r.t. all other params!
rho_G is collinear w.r.t. all other params!
rho_Gf is collinear w.r.t. all other params!
tau_c_ss is collinear w.r.t. all other params!
rho_tau_c is collinear w.r.t. all other params!
tau_h_ss is collinear w.r.t. all other params!
rho_tau_h is collinear w.r.t. all other params!
phi_b is collinear w.r.t. all other params!
Can they be identified separately?
Best,
Leonid.
