Hey issacnewton.

What are the specific hypothesis you are testing? Usually for a power test you will be testing say sigma^2 = a vs sigma^2 = b and if this is the case you will either find some measure getting power usually for specific values of a and b and not one that is algebraic or symbolic (like a formula) due to the complicated nature of the statistical distributions.

So do you have specific values for a and b and are the hypothesis tests I mentioned accurate or not?
