我正在努力学习Holt Winters指数平滑。在算法中，预测时涉及三个指数（水平，趋势，季节性）。
我的问题：
What is the interpretation of these 3 indices?
How do I differentiate between different values of these indices? For example, what is the difference between level 100 and level 200 or what is the difference between trend 2 and trend 5?
How do we initiate these values?
非常感谢任何帮助。
我从这个视频开始。但我的上述问题并未明确。 https://www.youtube.com/watch?v=VLlGO_fCdX0
