    Title: Application of Information Theory to Select Relevant Variables
    Authors: Lee, R. C. T.
    教師: 李家同
    Date: 1971
    Publisher: Elsevier
    Relation: Mathematical Biosciences, Elsevier, Volume 11, Issues 1-2, 1971, Pages 153-161
    Keywords: Information Theory
    Abstract: In this article we apply information theory to the multivariate data analysis problem. Given a dependent variable Y and any independent variable X, we can associate with X a number that would indicate the importance of X with respect to Y. This procedure enables us to select variables based on their importance. Two sets of data (upper abdominal pain and character recognition) are analyzed by this approach. The results indicate that this approach is feasible.
