e/Generalized Procrustes analysis

Information
has gloss	eng: The origin of generalized Procrustes analysis (GPA) has a strong basis in the comparison of research results across languages (terms from interviews, surveys, panels, etc). It was developed to permit statistical analysis of the results of free-choice profiling which allows respondents (such as sensory panelists) to develop their own terms for attributes that describe a range of products in their own words or language (Meullenet, Xiong, and Findlay, 2007). GPA is the only way to make sense of free-choice profiling data.
