In this manuscript we discuss sample size and power calculations for continuous outcomes.
More specifically, in the absence of DIF, the fit measure should be near a constant value independent of the sample size while, in the presence of DIF, the value should only quantify DIF without being affected by sample size.
The comparative percentage relative efficiencies increase as the sample size increases for the proposed adaptive estimators (Eq.
1 in this study), several tests of covariance matrices, including the LRT, are less powerful in small samples (n=10) and that the power of the tests increases with an increase in the sample size.
The development of this new method was triggered by the alarming observation that the RMSE of the estimated effective sample size could be as large as 60% of the effective sample size when using the original formula.

In this paper, we present a self-adaptive testing scheme for deciding the test sample size that facilitates optimal testing in the restricted scenario as mentioned above.
When using non-statistical sampling, auditors use their judgment to determine the sample size, to select the sampled items, and to determine if the account balance is within tolerable limits (AICPA, 1983).
The primary technical change was an increase of our sample size from 800 to 1,200 respondents beginning with this survey.
