This study introduces a new nonparametric method for comparing two groups experiencing repeated events. The approach is validated using locomotive brake repairs and patient bladder tumor data.

Area of Science:

  • Statistics
  • Biostatistics
  • Engineering Reliability

Background:

  • Analyzing recurrent event data is crucial in various fields.
  • Existing methods may have limitations for specific data structures.
  • Understanding event patterns aids in predicting system failures or disease progression.

Purpose of the Study:

  • To present a novel nonparametric statistical method for comparing two samples with recurrent events.
  • To provide a flexible and robust approach for analyzing time-to-event data with multiple occurrences.
  • To demonstrate the applicability of the proposed method in practical scenarios.

Main Methods:

  • Employs a nonparametric approach, avoiding assumptions about data distribution.
  • Focuses on comparing the rates or patterns of recurrent events between two independent samples.

  • Utilizes survival analysis principles adapted for recurrent event data.

    • Main Results:

    • The method effectively distinguishes between groups based on recurrent event occurrences.
    • Demonstrates reliable comparisons in diverse datasets, including engineering and medical applications.
    • Provides insights into the factors influencing the frequency or timing of recurrent events.

    Conclusions:

    • The developed nonparametric method offers a valuable tool for analyzing recurrent event data.
    • Applicable across disciplines, enhancing comparative studies of event processes.
    • Supports informed decision-making in maintenance, healthcare, and reliability engineering.
