Ah I think by IV you mean indicator variable, not independent variable.

In that case, as long as you have an ordinal variable with a
reasonable number of categories (more than 5) that has a reasonably
symmetric bell shape, things are probably OK with ML, though you might
want to use bootstrapping.
