The paper takes a different perspective and investigates the null hypotheses of no relevant changes, i.e. H0:\u2016\u03b81\u2212\u03b82\u2016\u2a7d\u0394, where \u2016\u00b7\u2016 is an appropriate norm. This formulation of the testing problem is motivated by the fact that in many applications a modification of the statistical analysis might not be necessary, if the difference between the parameters before and after the change point is small. A general approach to problems of this type is developed which is based on the cumulative sum principle. For the asymptotic analysis weak convergence of the sequential empirical process must be established under the alternative of non-stationarity, and it is shown that the resulting test statistic is asymptotically normally distributed. The results can also be used to establish similarity of the parameters, i.e. H1:\u2016\u03b81\u2212\u03b82\u2016\u2a7d\u0394, at a controlled type 1 error and to estimate the magnitude \u2016\u03b81\u2212\u03b82\u2016 of the change with a corresponding confidence interval. Several applications of the methodology are given including tests for relevant changes in the mean, variance, parameter in a linear regression model and distribution function among others. The finite sample properties of the new tests are investigated by means of a simulation study and illustrated by analysing a data example from portfolio management.<\/jats:p>","DOI":"10.1111\/rssb.12121","type":"journal-article","created":{"date-parts":[[2015,5,21]],"date-time":"2015-05-21T17:12:51Z","timestamp":1432228371000},"page":"371-394","source":"Crossref","is-referenced-by-count":51,"title":["Detecting Relevant Changes in Time Series Models"],"prefix":"10.1093","volume":"78","author":[{"given":"Holger","family":"Dette","sequence":"first","affiliation":[{"name":"Ruhr-Universit\u00e4t Bochum \u00a0 Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dominik","family":"Wied","sequence":"additional","affiliation":[{"name":"Technische Universit\u00e4t Dortmund \u00a0 Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2015,5,21]]},"reference":[{"key":"2023021709304086300_rssb12121-cit-0001","doi-asserted-by":"crossref","first-page":"817","DOI":"10.2307\/2938229","article-title":"Heteroskedasticity and autocorrelation consistent covariance matrix estimation","volume":"59","author":"Andrews","year":"1991","journal-title":"Econometrica"},{"key":"2023021709304086300_rssb12121-cit-0002","doi-asserted-by":"crossref","first-page":"128","DOI":"10.2307\/2951764","article-title":"Tests for parameter instability and structural change with unknown change point","volume":"61","author":"Andrews","year":"1993","journal-title":"Econometrica"},{"key":"2023021709304086300_rssb12121-cit-0003","doi-asserted-by":"crossref","first-page":"9","DOI":"10.1016\/0304-4076(94)01682-8","article-title":"Optimal change-point tests for normal linear regression","volume":"70","author":"Andrews","year":"1996","journal-title":"J.
