control_f(numer_grad = TRUE, improve_hessian = TRUE, eps = 1e-04)
Arguments
- numer_grad
whether to use numerical gradient
- improve_hessian
improve numerical hessian by using central difference estimation (O(eps^2) error)
default is forward difference estimation (O(eps) error)
- eps
eps for computing numerical gradient
Value
list of control variables
