你能帮我弄清楚为什么我得到一个错误吗?
最初我的数据看起来像这样:
> attributes(compl)$names
[1] "UserID" "compl_bin" "Sex.x" "PHQ_base" "PHQ_Surv1" "PHQ_Surv2" "PHQ_Surv3"
[8] "PHQ_Surv4" "EFE" "Neuro" "Intervention.x" "depr0" "error1_1.x" "error1_2.x"
[15] "error1_3.x" "error1_4.x" "stress0" "stress1" "stress2" "stress3" "stress4"
[22] "hours1" "hours2" "hours3" "hours4" "subject"
首先,我重塑我的数据,为geeglm做准备:
compl$subject <- factor(rownames(compl))
nobs <- nrow(compl)
compl_long <- reshape(compl, idvar = "subject",
varying = list(c("PHQ_Surv1", "PHQ_Surv2" ,
"PHQ_Surv3", "PHQ_Surv4"),
c("error1_1.x", "error1_2.x",
"error1_3.x", "error1_4.x"),
c("stress1", "stress2", "stress3",
"stress4"),
c("hours1", "hours2", "hours3",
"hours4")),
v.names = c("PHQ", "error", "stress", "hours"),
times = c("1", "2", "3", "4"), direction = "long")
- -(编者注:不确定下一个输出来自什么...)
[1] "UserID" "compl_bin" "Sex.x" "PHQ_base" "EFE" "Neuro" "Intervention.x"
[8] "depr0" "stress0" "subject" "time" "PHQ" "error" "stress"
[15] "hours"
然后我使用geeglm函数:
library(geepack)
geeSand=(geeglm(PHQ~as.factor(compl_bin) + Neuro+PHQ_base+as.factor(depr0) +
EFE+as.factor(Sex.x) + as.factor(error)+stress+hours,
family = poisson, data=compl_long,
id=subject, corst="exchangeable"))
我得到一个错误:
"Error in geese.fit(xx, yy, id, offset, soffset, w, waves = waves, zsca, :
nrow(zsca) and length(y) not match"
如果我删除变量.factor(error)和hours,geeglm不会抱怨,我会得到输出。该函数不适用于错误和小时变量。我检查所有变量的长度,它们是相等的。你能帮我弄清楚是怎么回事吗?
非常感谢!

我很确定这是鹅()中的一个bug,应该向
geepack的维护者问题在于失踪的处理
价值观。
如果看
dim(na.omit(dat[,c("id","score","chem","time")]))
一个在geese.fit()中,zsca被设置为等于矩阵(1,N,1),其中N被设置为
等于length(id)。但是id的长度为46,而响应y的长度为
通过消除数据的任何行来削减到长度44,其中
所涉及的变量缺失。所以有问题。
问题的解决需要重写一些代码
