Download Joinpoint Desktop Software

Thank you for your interest in using the Joinpoint statistical software for the analysis of continuous linear trends with change points, i.e. joinpoints. This version of the software is supplied with a graphical user interface for use interactively. Joinpoint is a Microsoft Windows application and can only be used on a Mac in conjunction with a Windows emulator.

Version (released April 16, 2018)

New Features

  • Added “Data Dependent Selection” as a new Model Selection Method option. This is an Alpha feature.
  • Added “BIC3” as a new Model Selection Method option.
  • Added the ability to select Parametric or Empirical Quantile methods for APC and Tau Confidence Intervals.
  • Two separate methods of the Empirical Quantile confidence interval calculations are now provided: Method 1 and Method 2. This is an Alpha feature.
  • Added the option to set the seed value used for generating random numbers during resampling under the Empirical Quantile method as well as an option to keep the seed constant or have it change with each cohort.
  • A new Joinpoint File Type was created. The Joinpoint Template (.jpt) allows users to save their Session settings, including variable locations, and then create a new session with a new data file. This allows users with multiple similar data files to easily recreate sessions.
  • Added a more advanced filter control to the Cohort Tree of the Output Window.
  • Added slope significance indicator on the Output Window graph when Log Transformation is No.
  • Added a new grid to the Model Selection tab of the Output Window which displays the Model Selection Method chosen.
  • Added a footer to the Output Window to display the Confidence Interval Method used.
  • Added examples on how to call the console version from a SAS or R program.
  • Right-click “Save As” for graphs now supports PNG and TIFF formats (for normal and high resolution graphs).

Bug Fixes

  • Changed the data file preview grid (on the Input Tab of the Joinpoint session) to allow keyboard navigation.
  • Removed Multi-Group Clustering group box from the Advanced Analysis Tools Tab of the Joinpoint session.
  • Improved the loading and processing of input data files.
  • Improved the display of formulas in the online help.
  • Fixed the High Resolution Graph to look more like the normal graph.
