Yes. This class is disorganized and the notes are confusing and not in order. But Professor Esfandiari is one of the most caring and helpful professors I have had at UCLA. She really cares about how her students are doing and willing to provide the guidance and spend the time that needed to work with her students. If you take this class, you will tumble through 30 page long lecture notes but if you put in the time you will be just fine!

Professor Esfandiari is an amazing teacher and a woman. She truly cares about student learning and helps hard working students by any means possible. She holds office hours multiple hours a week and she is always happy to meet students by appointment. I was going through something personal and she was extremely kind, understanding and she helped turn my life around.

The class material is not difficult but homework can be a bit long. Her lectures are clear and follow the book closely. The one thing I'd suggest is to proofread the notes to correct typos.

I learned a lot in this class. Professor Esfandiari is very knowledgeable, cares a lot about student learning, creates an atmosphere in which the students feel welcome, uses the data the result from her own research in teaching the class, uses her extensive consulting experience to show the real world application of the statistical methods taught, actively involved the students through in class exercises that she uses to check for student understanding, and treats students with respect.
The only improvement needed is better organization if the material and correction of typos.

HORRIBLE lady is teaching HORRIBLE class. Esfandiari is the Most crazy professor I ever met at UCLA. she doesn't know what she is taking about, lectures are all over the place, whatever notes she provides are a piece of crapp. she likes group work, shares students' personal problems with everybody else in the department which is insane. I am taking 101A only this summer but I am counting everyday, just hope it will end as soon as possible. awful lady

She is the worst worst WORST teacher in my life. She likes to make everything worse, exaggerating a student’s concern to max, share it with everybody in the department. I got an A but I HATE her. Have no idea why UCLA still keeps her

(Update: Her midterm and final were easy enough to bounce back the other complaints, but I believe everyone including myself had to self study most of the materials. )She is one of the worst professor I took in terms of teaching. Her notes are terrible and unreliable, and you should believe me and others about this(I did not before I actually took her). People kept complaining about mistakes in her notes but she still uses the same ones every quarter. The notes are not organized; font, size, notations are all randomly chosen. On top of that, she jumps back and forth between slides and files. Also, she doesn't follow her notes in order(if it has one). All add up to an extreme confusion about the topics. With a class with many different concepts and notations, and overlapped topics, statistics should be taught in an organized manner, and so far I feel like only professor M.Cha knows how to do it, not even professor Lew, yes the GOAT. I think you should a void her in a regular quarter because the confusion in 10 weeks will make you crazy and stressful during final time. Take her during summer if you have to.

Bit unclear and disorganized curriculum and lectures, but an awesome woman and extremely helpful and kind if you reach out to her in person. There is endless material to practice with for this class as well, so you have just about no excuse to be blown away by the exam content, despite the slightly unclear curriculum and topics. I also felt that I learned a great deal from this course-- Dr Esfandiari will teach you some cool things no doubt, but there are endless online materials that cover regression in R and the like. Overall, not too hard, not too stressful. and you can easily get the education you want from this course.

To be honest, she is not that bad. Like everyone else have said, she is a very kind women. When students have questions/problems, she will try her best to help. The only problem is that her lecture is not very organized. In my opinion, I would rather take her instead of Gould.
