The following code is an implementation of the method described in the following manuscript (available upon request):
Thompson, K.L. and S. Lin. 2016. A Robust and Efficient Statistical Test, Submitted.
About the Program
This code calculates the robust and efficient test (REST) statistic used to search for differentially expressed genes among cancer and normal patients. The method includes a hypothesis test to search for for heterogeneous differential expression in cancer samples that can guide the choice of an appropriate tuning parameter used in the REST statistic.
