Since the perturbed Hamiltonian is time-dependent, so are its energy levels and eigenstates. The simultaneous equation model requires a theory of reciprocal causality that includes special features if the causal effects are to be estimated as simultaneous feedback as opposed to one-sided 'blocks' of an equation where a researcher is interested in the causal effect of X on Y while holding the causal effect of Y on X constant, or when the researcher knows the exact amount of time it 2015-01-20 · Simultaneous Equations with multiplying The first three are just consolidation before then having to do some with multiplication of one or both equations.

### Overview (again) of Variational Method Approximation. We can always construct a variational energy for a trial wavefunction given a specific Hamilitonian. Etrial = ψtrial | ˆH | ψtrial ψtrial | ψtrial ≥ Etrue. The variational energy is an upper bound to the true ground state energy of a given molecule.

Systems of simultaneous equations and causal inference See also: Simultaneous equation models , Least squares , Maximum likelihood , Graphical models , and Causality In 1943 and 1944, Trygve Haavelmo put forward his ideas on the simultaneous equations model, arguing that systems of simultaneous equations should be central in econometric research.
