Description: Performs stability analysis of multi-environment trial
        data using parametric and non-parametric methods. Parametric
        methods includes Additive Main Effects and Multiplicative
        Interaction (AMMI) analysis by Gauch (2013)

        <doi:10.2135/cropsci1966.0011183X000600010011x>, genotypic
        confidence index by Annicchiarico (1992), Murakami & Cruz's
        (2004) method, power law residuals (POLAR) statistics by Doring

        index by Olivoto et al. (2019b)
        <doi:10.2134/agronj2019.03.0221>. Non-parametric methods
        includes superiority index by Lin & Binns (1988)

        stability by Huehn (1990) <doi:10.1007/BF00024241>, TOP third

        Functions for computing biometrical analysis such as path
        analysis, canonical correlation, partial correlation,
        clustering analysis, and tools for inspecting, manipulating,
        summarizing and plotting typical multi-environment trial data
        are also provided.
