We consider a unified procedure for detecting, localising and magnitude estimation of outlier and structure change in ARX process. The considered outliers are the additive outlier (AO) and the innovation outlier (IO) both in output and input variable. The structure changes allowed for are level shift and drift shift. The effectiveness of these procedure is demonstrated by analysing a numerical example
