Resumen
In this paper, repeated measurements (RM) experiment is used to detect the real differences of the agricultural rice production experimental data based on parametric analysis. The study conducted through the analysis of variance (ANOVA) for RM design as the variance-covariance matrix is uniform and it has also observed that sphericity is a special case of the variance-covariance matrix of the uniformity. The analysis requires degrees of freedom of univariate F-ratios need to be adjusted as the variance-covariance matrix shows neither uniformity nor sphericity assumption. The experimental data on rice production collected by Bangladesh Rice Research Institute (BRRI) fits the theoretical aspects of parametric analysis. Keywords: Repeated measures, ANOVA, univariate analysis, multivariate analysis.
