WAYNE A. TAYLOR<\/strong><br \/>Taylor Enterprises, Inc., Libertyville, IL 60048<\/p><p>Change-point analysis is a powerful new tool for determining whether a change has taken\u00a0place. It is capable of detecting subtle changes missed by control charts. Further, it\u00a0better characterizes the changes detected by providing confidence levels and confidence\u00a0intervals. When collecting online data, a change-point analysis is not a replacement for\u00a0control charting. But, because a change-point analysis can provide further information,\u00a0the two methods can be used in a complementary fashion. When analyzing historical\u00a0data, especially when dealing with large data sets, change-point analysis is preferable to\u00a0control charting. A change-point analysis is more powerful, better characterizes the\u00a0changes, controls the overall error rate, is robust to outliers, is more flexible and is\u00a0simpler to use. This article describes how to perform a change-point analysis and\u00a0demonstrates its capabilities through a number of examples.<\/p><p><a href=\"\/asa-2002-change-point-analysis-pdf\/\" target=\"_blank\" rel=\"noopener\">Read the full article&#8230;<\/a><br \/><a href=\"\/asa-2002-change-point-analysis-slides-pdf\/\" target=\"_blank\" rel=\"noopener\">View the slides here&#8230;<\/a><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"<p>DR.
