• Status (Sheet 3):
  =IF(Current_Stock <= Reorder_Point, IF(Current_Stock <= 0, "Out of Stock", "Low Stock"), IF(Current_Stock > Reorder_Point + Safety_Stock, "In Stock", "Low Stock"))
• Confidence Level (Sheet 2):
  =IF(ISTEXT(Trend_Factor), 0.4, IF(ABS(Trend_Factor) > 0.15, 0.6, IF(ABS(Trend_Factor) > 0.05, 0.8, 1)))
