"Is the Trend Changing? Joinpoint Regression Analysis"

Hyune-Ju Kim, Syracuse University
Michael J. Barrett, IMS, Inc.
Presented at the Fifteenth Annual Maternal and Child Health Epidemiology (MCH Epi) Conference
December 9-11, 2009 in Tampa, Florida

In this workshop, we will first provide an overview of the methodology and its statistical content. We will discuss how Joinpoint identifies the numbers of change-points and estimates the model parameters with their associated p-values. We also discuss various parameter settings in Joinpoint, focusing on what they are, when to use, and how to determine the parameter values. We will also discuss its extension to compare two or more groups of data in addressing questions such as if two groups share the same slope changes. Then, we will demonstrate Joinpoint software, including how to prepare the input data files, select the appropriate settings, and export and use of the results. We will also present some of the latest features such as Hudson's Method, AAPC, and Pair-wise Differences. Finally, we will present some examples, which are expected to highlight important characteristics and challenges in trend data analysis.
