In order to use estimate Standard Errors with the Abadie and Imben's method the MatchIt object needs to have a model matrix. The model matrix is created based on the subclasses given by the full matching procedure.
This function is experimental! Most methods for estimating standard errors are only documented for NN matching. Please use with caution!
