For complex models it might be best simply to simulate data and determine the power.

Cheers Wilhelm, thats what I'm looking into at the minute, but was hoping there may be some code around to help out.

Well, Alan, you have a specific model, a specific problem, specific constaints and specific aims. You just need to write it down... there won't be a general tool or code you can use (at least without changing or setting up a lot - what is as much work as coding the sim yourself).

So I could only give you a pseudocode, but this is too obvious and not helpful.

No problem, will just have to spend some time and create the simulations. Thanks for your help.

You are wellcome. Please ask again if you have any specific problem with this, e.g. with using a function or extracting a particular statistic or something like this. Good luck!
