Resumo: |
Box and Cox (1964) developed a numerical procedure to transform the response variable such that the transformed variable should be as closed as possible to the normal distribution. The introduction of a new class of non linear symetric transformed models aims to extended the Box and Cox models to a general class of symetric models. The new class of models inclued all the continuos symmetric distributions with a possible non linear structure to the mean, making possible the use of the new class of regression models. It was applied in the estimate of volumes of the Eucalyptus tereticornis clones, with 7,5 years, planted in the Experimental Station of Araripe of the Agronomic Institute of Pernambuco (IPA), in the municipality of Araripina, in the semiarid of Pernambuco. The non linear model used as pattern was the Schumacher and Hall model. The results indicates that the transformed model with t-Student erros with two degrees of freedon adjusted better to the data set. |
