Dear R-Helpers, I'm searching for an R package that will produce power analyses for linear Wald tests. I have conducted a thorough analysis and come up with a pile of negative results (I'm the King, baby). I found asypow, which applies to likelihood ratio tests. However, we generally have the power to do Wald tests, I just need to prove it so that we can publish it ;) If this is a "dumb" question (i.e., there's something inherent in doing the test that implies the power to do detect an effect, or published results for certain sample sizes), please let me know, it will save me a lot of time.
