Temporal dominance curves depict the proportion of panellists
who selected the attribute as dominant at a given time. Consistent
with Lenfant et al. (2009), the dominance rate for each product (i.e.,
the proportion of panellists who scored each attribute) is computed
at each point of time. High proportions indicate a consensus among
panellists to agree that a specific attribute is dominant at a given
time. These proportions are plotted against time for the different attributes in a Panel Dominance curve
