thank you for the info about the -ice- options -- the variables are
*not* interval censored -- only the top is censored (e.g., I have
the actual counts if they are less than 10, but have a value of 10
for any observation that has a count of at least 10; another example
is that I have actual age if less than 90, but anyone who is at
least 90 years of age has the value 90;
-ice- can handle intervals of the form [a,infinity), and you can also
impose an upper bound so that you don't generate implausibly high
values.
the count variable is definitely not normally distributed
As I said, as long as you can transform to approximate normality for
the imputation step, I think you'd be fine. You could then just
transform back to the original scale to fit your model.
