Hi there,
I am encountering this error when using sim after logit.mixed or
probit.mixed:
Error in qifunction(obj, x = x, x1 = x1, y = y, param = param, num = num)
: could not find function "setup.x.matrix"
This is with "ZeligMixed".
If I use ZeligMultilevel I get:
Error in array(x, c(length(x), 1L), if (!is.null(names(x))) list(names(x),
:
attempt to set an attribute on NULL
Toy example:
d <- expand.grid(y=rbinom(10,1,.33),x=rnorm(10,1),t=1:4)
z.out <- zelig(y~x+tag(1|t),data=d,model="logit.mixed")
sim(z.out)
thanks,
Yph
