academic的可以建模，但是没有low level的数据，从业的不懂什么是建模，但是有数

作为一个搞建模的，我说一下自己为什么我支持紫荆。
紫荆用的是observational data，一些重大events，或者是新闻 是“endogenous”的
，没法integrate到模型里面quantify。
而且，这种已经发生的events 应该是已经体现在data 里面的。紫荆只是try to make
sense of the data
with a model that potentially fits well and can have some out of sample
predictions.
不过，理论上是只有structural model estimation 通过counterfactual experiments
可以做

are easily wrong.
Actually "price" can be predicted quite well using GLR (for example,
if GE is $18 today, it is highly like it is within a range of $17 to
$19 tomorrow), but return is deemed as non-predictable. Read about
asset returns, that will help.
