33 rows Two-Sample Satterthwaite t Test Assuming Unequal Variances. The corrected sum of squares of the samples in group 1 plus the corrected sum of squares of the samples in group 2 ie. Feb 28 2014 Here is the code that answer that question.
Continuous Outcome with σ unknown R.
This procedure computes and compares the power achieved by each of several test. That there is no clustering between subjects or units of observation. Continuous Outcome with σ unknown R. In most cases we can easily verify.
