Description Usage Arguments Methods Examples
Model matrix form gmmModels
. It returns the matrix of regressors
or the instruments. In restricted models, it returns the reduced matrix
of regressors.

object 
Object of class 
type 
Should the function returns the matrix of instruments or the
matrix of regressors. For 
signature(object = "linearGmm")
Linear models with not restrictions.
signature(object = "nonlinearGmm")
Nonlinear models with not restrictions.
signature(object = "rlinearGmm")
linear models with restrictions.
signature(object = "slinearGmm")
System of linear equations with no restrictions.
signature(object = "rslinearGmm")
System of linear equations with restrictions.
signature(object = "snonlinearGmm")
System of nonlinear equations with no restrictions.

## Unrestricted model
model1 < gmmModel(y~x1+x2+x3, ~x2+x3+z1+z2, data=simData)
model.matrix(model1)[1:3,]
## Restrictions change the response
R < c("x2=2","x3+x1=3")
rmodel1 < restModel(model1, R)
rmodel1
model.matrix(rmodel1)[1:3,]
