We recommend using the term confidence interval function (CI function) instead of P-value function. CI functions effectively visualize point estimation, variability, and their relation to the null value.

Area of Science:

  • Statistical graphics
  • Data visualization
  • Biostatistics

Background:

  • Confidence intervals are crucial for statistical inference.
  • Existing graphical methods like P-value functions have limitations.
  • A unified graphical approach is needed to represent estimation and uncertainty.

Purpose of the Study:

  • To propose and advocate for the term "confidence interval function" (CI function).
  • To demonstrate the utility of CI functions in statistical analysis.
  • To evaluate the application of CI functions in various statistical contexts.

Main Methods:

  • Graphical representation of confidence intervals across a range of values.
  • Simultaneous depiction of point estimates, variability, and null value relationships.

  • Evaluation of CI functions in scenarios including effect modification, confounding, and meta-analysis.

    • Main Results:

    • The CI function effectively visualizes point estimation and variability.
    • It clearly illustrates the relationship between estimates and the null value.
    • CI functions are valuable for understanding effect modification, confounding, and meta-analysis.

    Conclusions:

    • The confidence interval function (CI function) is a superior term to P-value function.
    • CI functions offer a comprehensive graphical tool for statistical interpretation.
    • The use of CI functions can enhance understanding in diverse statistical applications.
