HW 1 of 3: Focus 100% of your commentary on the statistical evaluation of these works. Take the role as a reviewer of the statistical approaches on these methods. Really looking forward to seeing your thoughts – ps. Increasing sample size is rarely if ever the answer. No minimum page/word number – just give me your best effort, max would be about 750 words or so total. Choose one: 1 and 2, or 3 below.
