Is possible that if cov1 and cov2 are two physiological variables not known or hidden, and the following dependence exists: Eta1=a1*cov1+e1 Eta2=a2*cov2+e2 Eta3=a3*cov1+a4*cov2+e3 e1, e2 and e3 are independent errors Thus, when dependence of parameters and cov1 and cov2 are not modeled, eta1 and eta3 are correlated, eta2 and et3 are correlated but eta1 and eta2 are not.
