Wait, so we're supposed to impute the imputations? Isn't that just double-imputing? I feel like we're going down a rabbit hole here...

I'm going with C. Recalculating the imputations using the validation data alone ensures we're not introducing any bias from the training set. Simple yet effective!

Option D makes the most sense to me. Using both the training and validation data for the imputations will give us a more robust and unbiased model evaluation.

I disagree, I believe option C is the best approach. The imputed values should be recalculated using the validation data.

I think option A is correct. The imputed values from the training data should not be used in the validation data.
