Abstract
The DEViaN-LM is a R package that allows to detect the values poorly explained by a Gaussian linear model. The procedure is based on the maximum of the absolute value of the studentized residuals, which is a free statistic of the parameters of the model. This approach makes it possible to generalize several procedures used to detect abnormal values during longitudinal monitoring of certain biological markers. In this article, we describe the method used, and we show how to implement it on different real datasets.
