Resumo: | In several areas it is necessary to study and measure several random variables. A common problem is that at the end of the study it may be difficult to interpret the results of these various variables. In order to reduce the number of the random variables, the principal components method is done, which is directly related to the explanation of the covariance structure by means of a few linear combinations of the original variables under study. This paper presents and exemplifies the principal components method and presents practical problems of this method in the veterinary and neurosciences area. |
