⚠️ Be aware when you use xgboost in #rstats.

I was having trouble with constant performance measures when passing case weights (through #caret) in [0; 1]. Now, I am passing integer case weights and it seems to work fine.

@sharoz I do have concerns about how easy it is to produce bad analyses with #python.

But I feel similarly about #rstats packages like #caret - you don't need to know what a classifier is, in order to train one.

This might be controversial, but we need to ask whether making it so easy is a good thing; and whether there is an argument to be made for building-in a small degree of difficulty.

Far from gatekeeping, it would be a measure against poor analyses that might cause actual harm.
