matlab - 为什么 matbugs 永远不会停止运行？

Question

我可以在 WinBUGS14 中毫无问题地运行模型并获得结果，但是当我从 MatLab 运行相同的 WinBUGS 模型（如下所示）时出现问题。它看起来程序永远不会停止运行并且没有结果返回。

谁能帮我。任何建议将不胜感激。谢谢。

1) 我的 WinBUGS 代码 --- CHK_model.txt

model {
for(i in 1: N) {
CF01[i] ~ dnorm(0, 20)
CF02[i]  ~ dnorm(0, 1)
h[i] ~ dpois (lambda [i])
log(lambda [i]) <- beta0 + beta1*CF03[i] + beta2*CF02[i] + beta3*CF01[i] + beta4*IND[i]
}
beta0 ~ dnorm(0.0, 1.0E-6)
beta1 ~ dnorm(0.0, 1.0E-6)
beta2 ~ dnorm(0.0, 1.0E-6)
beta3 ~ dnorm(0.0, 1.0E-6)
beta4  <- log(p)
p ~ dunif(lower, upper)
}

2) 我的 MatLab 代码

@N t，非常感谢您的帮助。我不知道为什么我无法使用“发布您的答案”来回复您。所以我在这里回复：

我从一个网站 (http://code.google.com/p/matbugs/) 下载了 matbugs.m，根本没有碰过这个程序。

当我运行 Matlab 代码时（如我的帖子所示），计算转到 WinBUGS 接口并停在那里。弹出三个WinBUGS窗口：第一个是WinBUGS License窗口，第二个是Log窗口，第三个是Trap窗口。

1）这里是日志窗口；.... 数据加载 compile(3) 模型编译 inits(1,

2) 这里是Trap Wind ... (pc=764962F9H, fp=0028FB3CH) (pc=76496D39H, fp=0028FBB4H) (pc=764977C3H, fp=0028FC14H) (pc=76497BC9H, fp=0028FC24H) HostMenus.Loop [ 00003BDEH] .done BOOLEAN FALSE .f SET {0..5} .n INTEGER 0 .res INTEGER 0 .w HostWindows.Window NIL Kernel.Start [00002B8CH] .code PROCEDURE HostMenus.Loop

3) matbugs.m 的程序太长，无法在此处发布，但我使用的程序与此完全相同http://code.google.com/p/matbugs/source/browse/trunk/matbugs.m

再次感谢您的宝贵时间和建议！
