Resumo: A quadratic polynomial model was studied, using response surface method, with some additional variables included in the model, in order to obtain equations to evaluate the dependent variable behavior after the inclusion of the additional variables. The parameter estimators (treatment and regression) were obtained using the least squares method. An algorithm was developed to perform the statistical analysis, considering the model adapted to a complete factorial design with three factors and three levels. In addition, estimators of variance and covariance of the parameters and variance analysis were determined.

Os estimadores dos parâmetros (tratamentos e regressão) foram obtidos através do método dos quadrados mínimos. Desenvolveu-se a sequência de operações para a realização da análise estatística, considerando-se o modelo adaptado a um esquema fatorial completo para três fatores e três níveis equidistantes. Foram determinados ainda: os estimadores das variâncias e covariâncias dos parâmetros e a análise da variância.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária Brasileirade Morais, Augusto Ramalhoda Cruz, Vivaldo Francisco2014-04-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/15860Pesquisa Agropecuaria Brasileira; v.24, n.6, jun. 1989; 635-645Pesquisa Agropecuária Brasileira; v.24, n.6, jun. 1989; 635-6451678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/15860/9940info:eu-repo/semantics/openAccess2014-08-26T19:50:44Zoai:ojs.seer.sct.embrapa.br:article/15860Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-08-26T19:50:44Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
