A COMPARATIVE STUDY BETWEEN TWO ALGORISMS OF TRE PARAFAC MODEL

Abstract

In utitizing the PARAFAC model, when Dr. Harshman' s program is used, there seems to be too many steps involved in leading to the optimum solution. In order to avoid such complexities and difficulties, Dr. Hayashi has suggested that different, more fool proof method be used. A comparison was made between these two methods using data about the physical constitution of children. The results showed that these two methods yielded two different solutions. Yet the solution from Dr. Hayashi' s method was found to be much more under standable than from Dr. Harshman' s method.
