Fitting regression models to censored survival data.

M Hudec, H Platz

    Statistics in Medicine
    |April 1, 1983
    PubMed
    Summary

    This review covers regression models for censored survival data, including hazard rate and log-linear models. An application to oral cavity carcinoma analysis compares parametric and semiparametric methods.

    Area of Science:

    • Biostatistics
    • Medical Statistics
    • Survival Analysis

    Background:

    • Censored survival data analysis is crucial in medical research.
    • Various regression models exist for analyzing such data.
    • Oral cavity carcinoma studies require robust statistical methods.

    Purpose of the Study:

    • To review regression models for censored survival data.
    • To apply these models to oral cavity carcinoma data.
    • To compare parametric and semiparametric analysis results.

    Main Methods:

    • Review of multiplicative hazard rate models, log-linear (accelerated failure time) models, linear models, and polynomial models.
    • Application of selected models to a retrospective oral cavity carcinoma study.
    • Comparison of parametric and semiparametric analytical approaches.

    Main Results:

    • Demonstration of various regression models' applicability to censored survival data.
    • Insights from applying these models to oral cavity carcinoma.
    • Comparative performance of parametric versus semiparametric analyses.

    Conclusions:

    • Regression models offer versatile tools for censored survival data.
    • Parametric and semiparametric methods provide complementary insights.
    • The choice of model impacts the analysis of oral cavity carcinoma data.
