[R] boxcox alternative

Dear all, I am working with a set of variables that are very non-normally distributed. To improve the performance of my model, I'm currently applying a boxcox transformation to them. While this improves things, the performance is still not great. So my question: Are there any alternatives to

Re: [R] boxcox alternative

Dear Michael. The normality of _covariates_ is seldom relevant. The relevance of normality of the _response variable_ depends on the model assumptions. In case of linear models the only the **residuals** (and not the responses) are assumed to be normally distributed. Transformation of
