Conversation
- Added autocorrelation & lag effects (sales momentum) - Added seasonality evolution analysis (monthly, weekly, half-year trends, EOFY comparison) - Provides insights into year-over-year changes and sales cycles Signed-off-by: Yasmin Pokia <124057636+YP682@users.noreply.github.com>
- Added sale rate heatmap (month × weekday) normalized by observed days - Kept raw sales heatmap for comparison - Added YoY % change with absolute deltas for clearer seasonal pattern detection - Provides cleaner insight into seasonal patterns vs actual sale frequency Signed-off-by: Yasmin Pokia <124057636+YP682@users.noreply.github.com>
