### Re: Binary covariate and run time errors using the nlevel imputation template

Posted:

**Wed Sep 12, 2018 2:03 pm**Hi Chris,

I've copied and pasted several chunks of code below where I can see errors. The two school-level variables I'm attempting to include are school average KS1 and KS2 scores (for 150 schools) which are normally distributed, albeit left-skewed. There are approximately 4 schools with missing KS1 and KS2 averages. Hopefully the code will be meaningful, but I can provide more if that would be helpful. I also downloaded the imputed datasets from these runs (with the school-level variables included), and the results are implausible for the level 1 variables with missing data.
