Simultaneous equations models are a type of statistical model in which the dependent variables are functions of other dependent variables, rather than just independent variables. [1] This means some of the explanatory variables are jointly determined with the dependent variable, which in economics usually is the consequence of some underlying ...
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.
From our previous analysis, given that v = 0.25 and c = 1, the equation of the dashed line of simultaneity is t − 0.25x = 0 and with v = 0, the equation of the dotted line of simultaneity is t = 0. In general the second observer traces out a worldline in the spacetime of the first observer described by t = x / v , and the set of simultaneous ...
In mathematics, a set of simultaneous equations, also known as a system of equations or an equation system, is a finite set of equations for which common solutions are sought. An equation system is usually classified in the same manner as single equations, namely as a: System of linear equations, System of nonlinear equations,
In linear algebra, the Cholesky decomposition or Cholesky factorization (pronounced / ʃ ə ˈ l ɛ s k i / shə-LES-kee) is a decomposition of a Hermitian, positive-definite matrix into the product of a lower triangular matrix and its conjugate transpose, which is useful for efficient numerical solutions, e.g., Monte Carlo simulations.

A typical such equation is the equation of Fermat's Last Theorem x d + y d − z d = 0. {\displaystyle x^{d}+y^{d}-z^{d}=0.} As a homogeneous polynomial in n indeterminates defines a hypersurface in the projective space of dimension n − 1 , solving a homogeneous Diophantine equation is the same as finding the rational points of a projective ...
