"总算"?:)

I suspect you know 线性。I do not think so。

Linear prediction is the most basic predictive method in universe。

If you cut the length infinitely small， the result is curve。

Even so， linear formula： y = kx + a has two variables. If you keep change k and a, all prediction will eventually meet. Got it? :):)

So next time, stop to be ignorant to call other 线性思维. OK？ ：）
