请教SAS 中关于kalman filter的问题
0 个回复 - 1495 次查看
利用
kalman filter 求解beta:
公式如下:
y=beta1(t)*x1(t)+beta2(t)*x2(t)+...+betaN(t)*xN(t)+e1(t);
beta(t)=beta(t+1)+e2(t);
条件:beta1(t)+beta2(t)+....+betaN(t)=1 AND betai(t)>=0;
该如何实现呢 ...

紧急求助:关于kalman filter 中初值问题
1 个回复 - 2268 次查看
请问哪位知道
kalman filter 中初值是如何确定的?我用eviews做
kalman filter,发现初值对结果的影响比较大,是否要得到理想的结果就是不断修改初值?我的程序的初值有8个,如果没有修改初值的方法,只能通过不断循环 ...

Kalman Filter问题请教
0 个回复 - 1220 次查看
通常线性KF需要把问题分为 transition and measurement equations,Y(t) = alpha + beta * X(t) + error1
X(t) = mu + F * X(t-1) + error2
这里 X(t)是 unobservable latent series。
但如果X是部分可以观察到的 ...
