The SUR model can be further generalized into the simultaneous equations model, where the right-hand side regressors are allowed to be the endogenous variables as well.

The book marks the peak in the development of Chinese algebra, for it deals with simultaneous equations and with equations of degrees as high as fourteen.
43.
Simultaneous equation methods are used in econometrics to estimate models in which multiple interdependent variables of interest are determined by equations involving each other and exogenous variables.
44.
Converting a set of parametric equations involves eliminating the variable t from the simultaneous equations x = x ( t ), y = y ( t ).
45.
This differs from other proposed methods of socialist calculation, such as simultaneous equations, Taylor-Lange accounting prices, and the use of labor time as a measure of cost.
46.
When the bus overtakes the car, they are at the same distance at the same time-so we can solve the simultaneous equations and calculate T as 1 hour.
47.
But Shackle claimed that this type of reasoning based on an analogy between a static system of simultaneous equations and a dynamic process of " t�tonnement " was extremely misleading.
48.
This implied that the system of simultaneous equations was being used as a sort of shorthand for a result that was actually reached dynamically through a series of trials and errors.
49.
Unfortunately, this system of six simultaneous equations with six unknowns is undetermined, and the possibility of the origins of the three vectors oriented towards the three attraction points not coinciding explains why.
50.
The machine had twelve integrators ( compared to six of the original MIT machine ) and could calculate differential equations of the twelfth order, or two simultaneous equations of the sixth order.
