Theoretically, the most satisfying technique for dealing with errors in variables has been the use of instrumental variables. However, the operational difficulty of finding appropriate instrument has led to a lack of use of the technique, to the extent that theoretical discussions of errors in variables are even disappearing from the texts. This paper has developed a method of constructing instruments whenever one set of independent variables is measured without error and one set is measured with error.
