- How much missing data is too much? Multiple Imputation (MICE) R
If the imputation method is poor (i e , it predicts missing values in a biased manner), then it doesn't matter if only 5% or 10% of your data are missing - it will still yield biased results (though, perhaps tolerably so) The more missing data you have, the more you are relying on your imputation algorithm to be valid
- How should I determine what imputation method to use?
What imputation method should I use here and, more generally, how should I determine what imputation method to use for a given data set? I've referenced this answer but I'm not sure what to do from it
- What is the difference between Imputation and Prediction?
Typically imputation will relate to filling in attributes (predictors, features) rather than responses, while prediction is generally only about the response (Y) Even if imputation is being used to refer to filling in Y's the purpose is different; you're not using it for the primary purpose of getting a prediction for that Y

- Imputation of missing data before or after centering and scaling?
I want to impute missing values of a dataset for machine learning (knn imputation) Is it better to scale and center the data before the imputation or afterwards? Since the scaling and centering m
