说句良心话,winrats是一个非常非常优秀的软件!
有没有哪本书里有详细介绍DCC-GARCH模型的?最主要的是我希望我能看得懂。最重要的是我能作出一个结果来,并且知道怎么解读结果。
Dynamic conditional correlation MGARCH model
Sample: 1 - 2015 Number of obs = 2014
Distribution: Gaussian Wald chi2(1) = 2.21
Log likelihood = 17476.35 Prob > chi2 = 0.1374

就比如说上面这个结果,lambda代表什么?有什么特性等。。希望赐教。
