The equation type, behavioral, identity, or
instrument is described using one of the keywords
followed by the equation name. Coefficients in a
behavioral equation are identified by using the keyword COEFF> followed by a list of their names. If a specific variable in an equation is
to be specified as an endogenous variable, then they keyword ENDOGENOUS> followed by the name of the
variable may be used.
The actual form of the equation is specified by using
the keyword EQ> as shown in
the example below.
EQ> Y = C1 + C2*X2
+ C3*LAG(X3,3) + C4*LEAD(X4,5) +...
where Y is the endogenous variable (by default),
C1, C2, C3, C4,... are coefficients, and X2, X3, X4, ... are exogenous variables.
