“…The L‐PLS regression approach introduced by Martens et al (2005) is based on one single analysis combining all the three blocks of data together (i.e., sensory properties, consumers' degree of liking ratings, and consumers' attributes; Vinzi et al, 2007). The matrices X and Z are centered for properties and attributes respectively, while matrix Y is supposed to be centered with respect to both its rows and its columns (double centered).…”

“…L-shape data can be analyzed in different ways, see for example, Smilde et al (2022) and Vinzi et al (2007). Here, we will focus on a one-step approach called L-Partial Least Squares (L-PLS) regression, and a two-step procedure (TSP) using standard Partial Least Squares (PLS) regression methods along the horizontal and vertical direction in the L-shape separately.…”

“…In recent years, a number of data analysis approaches have been suggested to handle L-shaped 101 data set (see e.g. Vinzi, Guinot, & Squillacciotti, 2007). The first part of the present sub-section 102 will be devoted to the two-step approach (PLS regression, see e.g.…”

“…According to the lines introduced by Wold et al (1983), several researchers have been taken all these matrices into account by means of Partial Least Squares (PLS) regression methods (Martens et al, 2005;Esposito Vinzi et al, 2007. This approach has been specifically applied to sensory data, for clustering and classification purposes (Vigneau and Qannari, 2003), as L-PLS regression by Endrizzi (2008) and Plaehn and Lundahl (2006), among others.…”
