Missing Data Estimation using Principle Component Analysis and Autoassociative Neural Networks
Three new methods are used for estimating missing data in a database using Neural Networks, Principal Component Analysis and Genetic Algorithms are presented. The proposed methods are tested on a set of data obtained from the South African Antenatal Survey. The data is a collection of demographic pr...
