Tóm tắt

Một định nghĩa thay thế về khoảng cách được trình bày cho các quan sát được vẽ trong một biểu đồ ba phần và, nói chung, cho các quan sát trong một tập hợp dữ liệu thành phần. Định nghĩa này, phù hợp với hệ tọa độ tam giác của biểu đồ ba phần, được so sánh với các phép đo khoảng cách khác và cho thấy nó liên quan đến cấu trúc hiệp phương sai của dữ liệu thành phần. Sự khác biệt góc cũng được thảo luận ngắn gọn trong Phụ lục.
