The grdient (vector of first derivatives) of the objective function f (projected toward the feasible region if the problem is constrained) at the point x* is zero. The Hessian (matrix of second ...

For this subclass a sufficient condition for local optimality is determined. The condition is easily testable and fails to hold, in many cases, only if a better solution is obtained. Also, this ...

The conditional score function has previously been shown to generate the optimal estimating equation for a parameter of interest when the conditioning statistic is complete and sufficient for the ...
