请教用R语言的大神,为什么我的数据用GEE语句跑出来的结果找不到P值呢,也没有提示warning message,难道是语句搞错啦?
代码如下所示:
t <- gee(EPDS_910~SCSQ_PO+SCSQ_NEG+educational+CP_relation,id = ID,data = DATA_ORI_LONG,family = binomial,corstr='unstructured')
summary(t)
结果如下所示:
GEE: GENERALIZED LINEAR MODELS FOR DEPENDENT DATA

Call:
gee(formula = EPDS_910 ~ SCSQ_PO + SCSQ_NEG, id = ID, data = DATA_ORI_LONG,
na.action = na.omit, family = binomial, corstr = "unstructured")

那些robust,naive是什么意思呢,然后也没有可信区间和P值,是需要到哪里设置吗
