i did some multilevel model using gllamm with STATA/SE v11:

Code:

`gllamm y, i(kab) link(logit) fam(binom) adapt nolog`

Code:

`xi: gllamm y i.x1 i.x2 x3 i.x4 i.x5 i(kab) link(logit) fam(binom) adapt nolog`

Code:

```
factor variables and time-series operators not allowed
r(101);
```

Is there any error on my variables, how to resolve this error?

Thanks for the response
