Abstract
A broader version of this paper (H. Wold 1976), first presented at the European Meeting of Econometric Society, Helsinki, Finland, 23–27 August 1976, has been split in two parts, of which this is the first. A program paper for a project on “soft” modelling with latent variables that I initiated in late 1971, and which soon expanded into international collaboration, the Helsinki paper links up with the group report on our project presented at the Third World Congress of Econometric Society, Toronto, Canada, 21–26 August 1975 (H. Wold, edit. 1975). The present first part of the Helsinki paper summarizes the theoretical evolution of the NTPALS approach to “soft” modelling, with detailed exposition of some new contributions. The second part, soon to be published elsewhere, reviews the first applications of NIPALS “soft” models, generalizes the approach in various directions, and comments upon “soft” versus “hard” modelling.
