<p>This is a helper function for the bootstrap test. It computes the t-statistic in a fast way.</p>

The classical two-sample t-test works well for the normally distributed data or
data with large sample size. The tcfu() and tt() tests implemented in this package provide
better type-I-error control with more accurate power when testing the equality of two-sample
means for skewed populations having unequal variances. These tests are especially useful
when the sample sizes are moderate. The tcfu() uses the Cornish-Fisher expansion to achieve
a better approximation to the true percentiles. The tt() provides transformations of the Welch's
t-statistic so that the sampling distribution become more symmetric. For more technical details,
