Từ 1 trở lên — không tốt hơn giả định giá đứng yên
Vùng tô là khoảng tin cậy. Nếu vùng này rộng hơn nhiều so với mức thay đổi dự báo, con số điểm không nên được đọc như một mức giá cụ thể.
Đánh giá rolling-origin trên 101 điểm gốc, tổng 9090 lần dự báo out-of-sample.
MASE chia sai số tuyệt đối trung bình cho sai số mà dự báo naive mắc phải trên cùng chuỗi. Dưới 1 nghĩa là mô hình mang thêm thông tin; từ 1 trở lên thì không, dù MAPE trông đẹp đến đâu.
Sai số nở ra theo khoảng cách dự báo — đây là lý do khoảng tin cậy ngày thứ 30 rộng hơn hẳn ngày mai.
