In　this　paper,　we　investigate　the　estimation　and　testing　problems　of　partially　linear　varying-coefficient　errors-in-variables　(EV)　models　under　additional　restricted　condition.　The　restricted　estimators　of　parametric　and　nonparametric　components　are　established　based　on　modified　profile　least-squares　method,　and　their　asymptotic　properties　are　also　studied　under　some　regularity　conditions.　Moreover,　the　modified　profile　Lagrange　multiplier　test　statistic　is　constructed　under　additional　restricted　condition.　It　is　shown　that　the　modified　profile　Lagrange　multiplier　test　statistic　is　asymptotically　distribution-free　and　follows　a　Chi-squared　distribution　under　the　null　hypothesis.　Some　simulation　studies　are　carried　out　to　assess　the　performance　of　the　proposed　methods.　A　real　dataset　is　analyzed　for　illustration.　(C)　2011　Elsevier　B.V.　All　rights　reserved.
