control iteration, etc. for yags()

Description

yags can involve a nested iteration procedure with solutions to an auxiliary estimating equation Ua embedded in the standard NR. the iteration process is controlled by parameters set in this function.

yags.control(maxiter=15, tol=1e-04, verbose=FALSE, Ua.maxit=20, Ua.tol=0.001, 
      Ua.gridlo=0.1, Ua.gridhi=0.9, Ua.gridnpts=10, Ua.secantdel=0.01, 
      fixscale=FALSE)

Arguments

maxiter

bound on number of NR iterations

tol

convergence criterion for NR

verbose

should extra info on iterations be emitted?

Ua.maxit

max number iterations for auxiliary estimating equation solver

Ua.tol

convergence criterion for aux. solver

Ua.gridlo

aux solver starts with a grid search: lower starting point

Ua.gridhi

upper bound to starting grid

Ua.gridnpts

number of nodes in starting grid

Ua.secantdel

delta for secant solution

fixscale

is scale parameter fixed?
