    Summary

    This study introduces a new stepwise procedure for determining experimental structures and deriving analysis-of-variance tables. This method generalizes existing techniques for complex, multi-tiered experiments, demonstrated with a wine-tasting example.

    Area of Science:

    • Statistics
    • Experimental Design

    Background:

    • Traditional methods for experimental structure determination and analysis-of-variance (ANOVA) table derivation can be limited in complexity.
    • Generalizing existing procedures is necessary for analyzing sophisticated experimental designs.

    Purpose of the Study:

    • To present a novel stepwise procedure for obtaining experimental structures.
    • To establish rules for deriving ANOVA tables from these structures.
    • To extend existing methodologies to multi-tiered experiments.

    Main Methods:

    • A stepwise procedure involving the division of factors into groups is proposed.
    • This method generalizes Nelder's approach for multi-tiered experimental structures.
    • The procedure's application is illustrated using a wine-tasting experiment.

    Main Results:

    • A clear, stepwise method for experimental structure determination has been developed.
    • Rules for generating the corresponding analysis-of-variance table are provided.
    • The generalized procedure accommodates complex, multi-tiered experimental designs.

    Conclusions:

    • The proposed procedure offers a systematic approach to analyzing multi-tiered experiments.
    • It provides a robust framework for deriving ANOVA tables from complex experimental structures.
    • The method is applicable to various fields, as shown by the wine-tasting example.
