Miles is easily one of the best professors I have had at UCLA. I came into this class terrified of coding and even just looking at R from my experience in stats 20, and now coming out of it feel confident with coding in R and even motivated to learn more languages. The class isn't super easy and the homework definitely is time consuming and challenging but they are definitely doable and you learn a lot from it. The midterm was far more difficult than the final for me personally, but across the board all of Miles homeworks and exams are very fair.

I really like Miles and this he is a great professor however this class is hard. He screen records all of his lectures so you can go back if you miss one or need to review but he does take attendance in class. He gives 6 homework assignments and you have about a week and a half to do each. START EARLY. They are tough and take a long time to do. Go to your TA for help. Miles is very strict about not looking at other student's code but the TA can be more lenient. His midterm is difficult but he gives a practice midterm and the structure and types of questions are basically the same. The material taught after the midterm is totally different (less coding heavy and more concept-based). His final is not at all like the midterm (not cumulative) and is much easier. Overall I really enjoyed this class even though it was difficult.

Somehow, the stats dept has the worst lecturers for the proof based classes, but for the coding side, they have the best professors around. Like Tsiang, Chen is one of my favorite professors here at UCLA.

His lectures, while potentially dry, are actually interesting, and you build on a lot of the concept you learn from Stats 20. You start going into optimization techniques, different common packages, and some object oriented topics.

Chen may come off cold in office hours, but tbh, the questions people ask him are kinda dumb. He's not going to troubleshoot your code, nor blatantly tell you how to do it. And honestly, his homework is definitely doable - you just have to understand the notes front and back, and know how to apply it(basically, don't be lazy). But he's an interesting person, and once you start talking to him, it's really chill. He's very open to helping with letter of recommendations, and is an interesting guy(loves basketball, grew up in LA, and had a crazy life). He actually cares about his students, telling you to sleep, letting you skip some classes without penalty, etc. Just don't try and cheat his attendance system - it's barely worth any points, and it's worse to be caught skipping and forfeiting all your attendance points for the quarter.

I think we learned some useful algorithms and techniques in this class that can be applied outside of the classroom. Professor Chen is super clear and is a good lecturer. His assignments can be tough, but he makes sure to give ample time to complete them. His midterm was quite challenging, as it required that you recall super specific details about R, but he was very considerate and curved the test to what he believed was fair. His final was much easier; you study his lectures and you will be golden. Overall, this class was enjoyable and pretty laid-back. Prof Chen is also a very caring professor, as with many other professors in the stats department!

Okay, I can see why everyone likes Chen. His class is very well done, and all of his content is very clearly explained. The first half of the class is all about how to program in R, and I think that I understand the material much better having learned it from Chen than when I learned it earlier from Lew. Chen is really good for the first part, and the second part is all numerical methods and sampling techniques, which are really easy. Exam wise, the midterm wasn't that hard, but yeah like everyone says, it is based on really small details, so it requires a development of a certain type of R intuition. I really liked the piazza system. The class was made a lot easier with the piazza system, as everyone really bought into it so if there was something tricky on the homework, you could figure it out. Overall, the homeworks could be difficult at times, but as long as you start them early, it's fine. Yeah, class is fine, Chen is a great professor, the homework can be difficult but are manageable, and the exams aren't too bad. A solid upper div.

Assignments are really hard. It usually takes me more than 7 hours to do one project. No homework scores will be dropped and each homework is worth 7% of the final grade. So, if you are taking this class, start early on homework. The professor usually posts homework 1 or 2 weeks before it's due.The monopoly one is extremely hard. Participation is worth 3%. People ask/answer a lot of questions on piazza, which was pretty helpful. Professor Chen is definitely a great lecturer. But this class is pretty hard in my opinion.

I've taken three classes with Professor Chen and I would say this one is the most interesting ones. For the assignments, you are required to build your own tic-tac-toes and Monopoly game with R. I admit that it took me a long time to finish these assignments, but I would say it definitely worth it. His lectures are well-structured and assignments are well-designed for students to understand the concepts. The midterm was a bit hard but the final exam was very fair. As long as you study the notes before the final, you will be good. Overall, I highly recommend STATS 102A with Professor Chen. Definitely one of the best professors at UCLA.

No comment.

Great professor who really cares about his students. Fav professor

Professor Chen's exams and homework are hard. But they teach you how to apply your knowledge, which makes the process of completing his assignments highly rewarding. He is approachable during office hours and clear in his lectures. Don't be afraid to ask for help! If you are willing to put in that extra effort, the class will definitely teach you a lot.
