Description Usage Arguments Value
This function generates the matrix and vectors associated with the monotonicity constraints declared by the user. It takes in a grid of the covariates on which the shape constraints are defined, and then calculates the values of the MTR and MTE over the grid. The matrices characterizing the monotonicity conditions can then be obtained by taking first differences over the grid of the unobservable term, within each set of values in the grid of covariate values.

A0 
the matrix of values from evaluating the MTR for control observations over the grid generated to perform the audit. This matrix will be incorporated into the final constraint matrix for the monotonicity conditions. 
A1 
the matrix of values from evaluating the MTR for control observations over the grid generated to perform the audit. This matrix will be incorporated into the final constraint matrix for the monotonicity conditions.

a list containing the point estimates and gamma components associated with each element in the Sset.

Name of unobserved variable. 
gridobj 
a list containing the grid over which the monotonicity and boundedness conditions are imposed on.
