We propose a new data-driven procedure of model selection based loss estimation and valid for the whole family of spherically symmetric distributions, allowing for dependence between noise components. We give explicit formulas for the Firm Shrinkage estimator, and we compare by simulation our results in terms of selection with the classical AIC, BIC and leave-one-out cross-validation.
