When we should use Replacement node and when use Impute node?
Thanks.

Tom, at a high-level the Replacement node allows you to assign/replace or trim values in your data. For example you may want to trim the tails of your distribution to tighten your analysis. You could then use an Impute node for example. The Impute node essentially replaces missing values in your data set. As you may know, if values are missing in your modeling set, observations are often excluded from the analysis.
