    Area of Science:

    • Biostatistics
    • Clinical Data Analysis
    • Time Series Analysis

    Background:

    • Accurate group discrimination is crucial in clinical settings.
    • Existing methods often rely on single time-point data, limiting their scope.
    • Multivariate response curves provide rich temporal information.

    Purpose of the Study:

    • To develop a novel method for discriminating between two groups based on multivariate response curves.
    • To create a solution that utilizes the historical data of response curves.
    • To offer a dynamic and clinically applicable approach.

    Main Methods:

    • Linear interpolation between successive observations to define response curves.
    • A descriptive statistical approach accounting for the temporal sequence of data.
