evaluate its performance for various data models. The only difference will be in
the raw data PDFs p (y|H ) and p (y|H ) assumed in the first step. However,

changes to these PDFs ripple through the entire process, changing the likelihood
ratio, then the sufficient statistic and thus the detector design, the threshold
setting, and finally the detection performance.
