Description: Pooled analysis of a series of designed experiments
        repeated over locations, seasons or years, where
        treatment-by-environment interaction is of primary interest.
        One design-specific function call performs environment-wise
        analysis of variance, formal testing of homogeneity of error
        variances, an optional variance-stabilising transformation,
        pooled analysis of variance with the correct error stratum for
        every effect, and multiple comparison of means. Five classical
        designs are supported: completely randomised ('PooledCRD()'),
        randomised block ('PooledRBD()'), Latin square ('PooledLSD()'),
        split plot ('PooledSPD()') and strip plot ('PooledStPD()').
        Homogeneity of error variances is assessed by Bartlett's test
        computed on the environment-wise error mean squares as in
        Bartlett (1937) <doi:10.1098/rspa.1937.0109>, and by the
        median-centred Brown-Forsythe form of Levene's test
        <doi:10.1080/01621459.1974.10482955>, which is robust to
        non-normality. When variances are heterogeneous, Aitken's
        transformation (division of each observation by the square root
        of the error mean square of its own environment) may be
        applied, and treatment means are reported on both the
        transformed and the original scale. For split plot and strip
        plot designs every effect is tested against its proper error
        term, and mean separation uses the error mean square and
        degrees of freedom of the corresponding stratum. The
        statistical theory is given in Cochran and Cox (1957,
        ISBN:9780471162032), Gomez and Gomez (1984,
        ISBN:9780471870928), Dean et al. (2017)
        <doi:10.1007/978-3-319-52250-0> and Ruiz et al. (2024)
        <doi:10.1007/978-3-031-65575-3>.
