How does the 'WOE' method work and what are its key options?

The 'WOE' (Weight of Evidence) method groups variables by maximizing the Information Value (IV). Key options include 'woeAdjust' to handle bins with zero events or non-events, and 'woeDefinition' which can be set to 'EVENT' (ln(event/non-event)) or 'NONEVENT' (ln(non-event/event)).
