The Direction Field Method

日期:2014/02/10

The Direction Field method is used to find the shape of the function that yields a field of slopes going through various points. (Here is a lecture about it on youtube). One wonders if it might be useful to use it to find the shape of a predictive function during the remaining part of a period. For example, using the changes on each of the previous 4 days to predict the change of the fifth day. One has explored some tendencies in that direction without much success but finds it opens up some interesting speculative ideas. In any case, it's a nice foundation to put in ones' Ken, especially for those who like geometry.
