The idea of this exercise is to explore this concept by focusing on the “product by session” interaction and the “product by panelist” interaction. csv from the book website. - Run the panelperf function on the imported data set using the default options. For which attributes do you observe a significant product by session interaction? - For these attributes, apply the graphinter function to “visualize” that interaction. Which product has not been assessed the same way from one session to the other?
