hallt implements a skewness adjusted bootstrapped t-statistic procedure. This is implemented in Eventus software for event studies as the skewness adjusted transformed normal test. skewt implements the skewness adjusted bootstrapped t-statistic procedure as in Lyon, John D., Brad M. Barber, and Chih-Ling Tsai, 1999, "Improved Methods for Tests of Long-Run Abnormal Stock Returns" The Journal of Finance 54, no. 1:165-201. Users can save the skewness adjusted bootstrapped t-statistics and also specify the proportion of the sample to use for the bootstrap.
