Different approaches for handling L-shaped data are compared for the first time in a study 17 conducted with Norwegian consumers. Consumers (n = 101) valuated eight different yoghurt 18 profiles varying in three intrinsic attributes such as viscosity, particle size, and flavour intensity 19 following a full factorial design. Sensory attributes, consumers' liking ratings, and consumer 20 attributes were collected. Data were analysed using two different approaches of handling L-21 shaped data: approach one used two-step Partial Least Square (PLS) Regression using L-shaped 22 data including the three blocks such as sensory attributes, consumers' liking ratings, and 23 consumer attributes, while approach two was based on one-step simultaneous L-Partial Least 24 Square (L-PLS) Regression model of the same three blocks of data. The different approaches 25 are compared in terms of centering, step procedures, interpretations, flexibility, and outcomes. 26 Methodological implications and recommendations for academia and future research avenues 27 are outlined. 28
