Description
Summary:The important thing in vehicle engineering is how well the car protected a driver and passenger during the crash. In this case, there are many variables that might be associated with the car protection system. The association of these variables can be analyzed by multiple correspondence analysis via Burt matrix. By performing an eigen-decomposition on the transformed Burt matrix, we can determine the correspondence plot that visualize the association between variables in a reduced dimension space. While some researchers' consideration on quantifying this association and visually depicting it, we interest to notice the reliability of the plot in representing the association. In this paper, we shall only consider the reliability by describing circle confidence regions for each point in a low-dimensional correspondence plot. The application on crash car protection data sets is given.
