Description: Analysis of variance for the experimental designs used in
    agricultural research, with the correct error term for every stratum,
    standard error of mean (SEm), standard error of difference (SEd),
    critical difference (CD), coefficient of variation (CV) and letter
    groupings: completely randomized design (CRD), randomized complete
    block design (RCBD) with missing plots, Latin square, two- and
    three-factor factorials, split-plot designs (including factorial main
    or sub-plots), split-split-plot and strip-plot designs, and combined
    analysis over environments. Also covers the augmented randomized
    complete block design with adjusted means and genetic parameters
    (Federer, 1961 <doi:10.2307/2527837>), alpha lattice designs with
    intra-block or residual maximum likelihood (REML) analysis (Patterson
    and Williams, 1976 <doi:10.1093/biomet/63.1.83>) and repeated measures
    with Greenhouse-Geisser and Huynh-Feldt corrections and covariance
    structure models. Mean comparisons (least significant difference,
    Duncan, Tukey, Student-Newman-Keuls, Scheffe, Bonferroni and Dunnett)
    follow Gomez and Gomez (1984, ISBN:0471870927), with letters assigned
    by the algorithm of Piepho (2004) <doi:10.1198/1061860043515>.
    Stability analysis includes Eberhart and Russell (1966)
    <doi:10.2135/cropsci1966.0011183X000600010011x> regression, additive
    main effects and multiplicative interaction (AMMI), Finlay-Wilkinson,
    Shukla, Wricke, coefficient of variation and Lin-Binns methods, and
    genotype plus genotype-by-environment (GGE) biplots (Yan et al., 2000
    <doi:10.2135/cropsci2000.403597x>). Further tools compute growing
    degree days, helio-thermal and photo-thermal units, crop growth rate,
    relative growth rate, net assimilation rate, leaf area index and leaf
    area duration, harvest index, yield gaps with the technology index,
    nutrient use efficiency, quadratic, plateau and Mitscherlich response
    curves with the economic optimum dose, benefit-cost ratio,
    correlation, principal component, path and structural equation
    analysis, publication tables for many traits and figures.
