We consider products of gaussian \u201cpancakes\u201d equally elongated in all directions except one and prove that the maximum likelihood solution for the model gives rise to a minor component analysis solution. We also discuss the covariance structure of sums and products of gaussian pancakes or one-factor probabilistic principal component analysis models. <\/jats:p>","DOI":"10.1162\/089976602753633439","type":"journal-article","created":{"date-parts":[[2002,7,27]],"date-time":"2002-07-27T11:58:45Z","timestamp":1027771125000},"page":"1169-1182","source":"Crossref","is-referenced-by-count":14,"title":["Products of Gaussians and Probabilistic Minor Component Analysis"],"prefix":"10.1162","volume":"14","author":[{"given":"C.
