momentStrength(object, theta,
vcovType=c("OLS","HC","HAC","CL"))

object 
An object of class 
theta 
Coefficient vector at which the strength must be
measured. It does not impact the measure for objects of class

vcovType 
Type of covariance matrix used to
compute the Ftest of the firststage regression. For 
signature(object = "functionGmm")
Not implemented yet. In that case, we want some measure of the rank of the matrix of derivatives.
signature(object = "formulaGmm")
Not implemented yet. In that case, we want some measure of the rank of the matrix of derivatives.
signature(object = "linearGmm")
It returns the Ftest of the first stage regression. It is a measure of the strength of the instruments.
signature(object = "rlinearGmm")
Returns nothing for now.
signature(object = "nonlinearGmm")
Not implemented yet.
