Abstract in Portuguese
O presente trabalho trata da análise conjunta de experimentos conduzidos em blocos incompletos balanceados (BIB) com alguns tratamentos comuns a todos os experimentos, possuindo não necessariamente os mesmos parâmetros de um experimento para outro. Os tratamentos pertencentes a todos os experimentos são designados de “tratamentos comuns” e os restantes, os quais ocorrem em somente um dos experimentos, de “tratamentos regulares”. O objetivo foi justificar os fundamentos teóricos da análise da variância e testes de significância derivados para este tipo de ensaio. O modelo matemático adotado foi: (Descrito na Dissertação). Sob essas condições foram determinados: o sistema de equações normais, os estimadores dos efeitos ajustados de tratamentos, a matriz de dispersão dos efeitos de tratamentos, as somas de quadrados, a variância da estimativa dos contrastes possíveis entre duas médias de tratamentos, além de ser dado um procedimento para a obtenção da soma de quadrados para a interação e para as esperanças matemáticas das somas de quadrados. Um exemplo numérico é apresentado para ilustrar a aplicação das fórmulas e procedimentos apresentados neste trabalho.
Title in English
Combined analysis of experiments in balanced incomplete block designs with some treatments in common
Abstract in English
The present work deals with the combined analysis of a group of experiments in balanced incomplete block designs (BIB) with some common treatments to the whole set. The experiments may not have the same parameters. The objective of this dissertation was to justify the theoretical basis of the variance analysis and derived significance tests for this type of combined analysis of experiments with some treatments appearing in the whole set of experiments (common treatments), and the others, in only one of the experiments (regular treatments). The following mathematical model was considered: (See Dissertation). Under the given conditions, the solution of the normal equations, the estimators of adjusted treatments effects, the dispersion matrix for treatment effects, the sum of squares, the variances of the four different types of contrasts among treatments effects were obtained. In addition, a procedure to obtain the sum of squares of interaction and expectations of sum of squares is also presented.
