我也在寻找这样的大侠

要用卡尔曼滤波做一个东西，可是不太懂啊

那位高手请帮忙，先谢了

There are a lot of references for Kalman filters. The best source certainly is Peter S. Maybeck: ..Estimation and Control (first volume). Others would be Gelb: Applied optimal estimation, Jazwinski: Optimal Filtering,...

GaussX

Gaussx incorporates a full featured set of professional, state of the art, econometric routines that run under GAUSS. These tools can be used within Gaussx, both in research and in teaching. Alternatively, since the GAUSS source is included, individual econometric routines can be extracted and integrated in stand-alone GAUSS programs.

Kalman Filter

Analysis with the Kalman Filter allows for the estimation of state vectors, with smoothing, time varying transition matrices (ie. each element is a function), and the estimation of the elements of the Kalman matrices using ML. Stochastic Volatility models (SV) are estimated using quasi ML based on a Kalman Filter model.

eviews里有，用来估计状态空间模型的

多谢各位

我开始喜欢上这个网站了

请问谁用过eviews来估计状态空间模型

能培训我一下么，具体操作上

请你吃饭

拜托了
