Looks okay. I understand this it to make RateStatistic a RealVector? But when is that actually needed? It just goes into a logger normally doesn't it? So it can still be a function since loggers aren't part of the model and strong typing only needs to be enforced for model components?

Because it uses a deprecated class, which was replaced by strong typing when tracing the inheritance chain. In addition, I presume Function will be removed in future with all deprecated classes.

Removing the old RateStatistic means old XML cannot run any more.

the old (deprecated) RateStatistic would not be removed, unless Function is removed as well as all deprecated classes using old Parameter.
