Tanya Byker
Byker is truly amazing. Regression is a hefty course but taking it with Byker helped me a lot. She is tough but supportive at the same time, explains concepts in ways you can understand, and provides tons of extra hours for help. Problem sets can be long and exams are almost half of the final grade but her course is manageable. No final exam.
Professor Byker is very enthusiastic about what she teaches and does a great job teaching her students. Her lecture-focused classes with in-class activities was very helpful. She also is very helpful outside of class whenever you need extra help.
Professor Byker is very nice and enthusiastic about her profession. I was intimidated to take this class, but it is not as bad as I thought. Everything she wants she makes very clear, and if you go to office hours the work gets easier.
