objFunction: Internal functions for constrained minimization

Description

Groups of functions used for the constrained minimization problem arising in the computation of the likelihood ratio test statistics.

Usage

objFunction(x, cst)
gradObjFunction(x, cst)
symMatrixFromVect(x)
ineqCstr(x, cst)
jacobianIneqCstr(x, cst)
eqCstr(x, cst)
jacobianEqCstr(x, cst)

Value

value of the objective function, its gradient, and the set of inequality and equality constraints

Arguments

x

A vector

cst

A list of constants to be passed to the optimisation function

Functions
