> Hi guys,
> 
> I am running Ridge regression on a dataset (predicted variable = y; GDP,
> HPA and FX are regressors). I found that lm.ridge() can perform the ridge
> regression given any value of lambda (i.e. the ridge parameter). However,
> in order to choose the best results, I need to select the model output
> corresponding to that lambda which optimizes some logically defined GCV
> criteria. I thought there would be some in-built funcion in R Studio for
> this, but could not find one. Also, I am not being able to write the
> required code for this. Any help here will be appreciated. I have
> attached
> the data in case it is required.
