This study introduces a new permutation test for comparing receiver operating characteristic (ROC) curves with continuous unpaired data. Simulations were used to evaluate the test's performance for unpaired continuous data analysis.

Area of Science:

  • Statistics
  • Biostatistics
  • Machine Learning

Background:

  • Receiver Operating Characteristic (ROC) curves are widely used for evaluating binary classification models.
  • Existing statistical tests for comparing ROC curves are often limited to paired continuous data.
  • A need exists for robust statistical methods to compare ROC curves with unpaired continuous data.

Purpose of the Study:

  • To extend the concepts of a previously developed permutation test for paired continuous data.
  • To introduce a novel permutation test specifically designed for continuous unpaired data.
  • To investigate the statistical properties of this new permutation test through simulation studies.

Main Methods:

  • Development of a permutation test algorithm for unpaired continuous data.

  • Application of the permutation test to simulated datasets.
  • Evaluation of test performance using simulation-based analysis.

    • Main Results:

    • The developed permutation test is applicable to continuous unpaired data.
    • Simulation results provide insights into the properties of the new test.
    • The study validates the utility of permutation testing for ROC curve comparisons in unpaired data scenarios.

    Conclusions:

    • The proposed permutation test offers a valuable tool for comparing ROC curves with continuous unpaired data.
    • This method enhances the statistical analysis capabilities in fields utilizing ROC curve evaluations.
    • Further research can explore the application of this test in diverse real-world datasets.
