The requirements for timely information on the reliability of product components and materials facilitate the use of accelerated degradation test (ADT). The ADT approach supports the experimenter in drawing quick inference on the lifetime distribution of testing units at normal use condition. This paper provides an Excel add-in program (called RExADT) for analysis of ADT data. RExADT is designed to support two popular ADT approaches: single-stage and two-stage approach. RExADT is implemented in Visual Basic for Applications (VBA) and R based on the R-EXCEL environment. RExADT is expected to help the users with diverse backgrounds perform the ADT analysis conveniently with a familiar graphical user interface in Excel.
