R Question

I know that one can get the predicted values (in original scale ~ probability) and their SE for the fixed effects with AICcmodavg, but I'm trying without any success... Can someone help me with that? Thanks in advance

`library(lme4)`

(gm1 <- glmer(cbind(incidence, size - incidence) ~ period + (1 | herd),

data = cbpp, family = binomial))

fixef(gm1)

library("AICcmodavg")

predictSE(gm1,

newdata=as.data.frame(period=c("period1","period2","period3","period4")),

type="response",

se.fit=TRUE,

level=0,

print.matrix=F)

Answer Source

It would be better to read `levels(cbpp$period)`

, and not `as.data.frame()`

but `data.frame()`

```
predictSE(gm1,
newdata = data.frame(period=c("1", "2", "3", "4")),
type = "response",
se.fit = TRUE,
level = 0,
print.matrix = F)
```
