Best statistics teacher I've ever had
Peter is a lifesaver! I needed statistics help with my Master's thesis, and he was able to quickly understand the data I'm working with, suggest statistical tests that would be a better fit, and explain these tests in a very easy-to-understand manner! His teaching style helped me understand stats more quickly than any professor I've ever had. He was also able to identify certain biases and where the statistical results might be misleading, which helps me avoid several tough questions that could have arisen during my thesis defense. He is a fantastic tutor and I recommend him to everyone!

Knowledgeable and informative
Peter helped me go over my cluster analysis and really helped me to better understand the process and results. We also had a great conversation on future academic paths and opportunities. I'd highly recommend Peter as a tutor and advisor.

Accessible explanations!
Peter demonstrates the intuition behind concepts. Solving becomes simpler when Peter is providing foundational knowledge. He helped me with my graduate school coursework on Bayesian Statistics.

Knowledgeable and patient tutor
Peter is extremely knowledgeable with the subject. Very patiently, step-by-step he worked through each problem. He understood the urgency of the situation and made time the very next day. Just to have a tutor who is proficient is very reassuring. Very methodical and makes the student understand the concepts. Highly recommended.

Superb data scientist
Peter is my go-to guy for data science; he provides clear explanations and is very responsive. He is very well versed in both R and Python. Highly recommended!

Outstanding tutor
Quant. Peter L. is the best tutors I have ever had. I learn so much, thanks to him! He is patient and understandable. He has so much knowledge and experience. What a brave person. I am so pleased I got to know him!

A Real Teacher!
I’m a Master’s international student who never had an Econometrics course before. I have struggled with the course for a while as the course’s pace was too fast for me. I met Peter twice before my midterm and he actually explained almost the entire course in two sessions! He illustrated the concepts in real life easy to understand examples. He was patient, understanding, and he was also funny. Thanks to Peter, I actually got an A+ on my midterm!

Knowledgeable and helpful tutor
Peter helped me with Econometrics, he helped me by providing answers to my questions both by words and numbers, so I have more options to absorb the material that way.

Very Knowledgeable Tutor
I was taking an exceedingly difficult Partial Differential Equations class for the undergraduate-level. I started off with some other tutors which got me through most of the course, but when we started covering Fourier Transforms and Green's Functions to solve PDE's, I had to turn elsewhere for help due to the time constraints on the homeworks. I found Dr. L. and he was able to help me quickly and even offer some insight into the methods involved. After purchasing the book, he was able to help me within 1-2 days time of any request and got me through most of the problems each time we met. The one time we did not have a good session (because we met very late and he had had a long day), he waived it off as a free lesson instead. It was a very tough course but Dr. L. helped me get through the toughest parts of it, so I highly recommend him for anyone else struggling through PDEs or classes of similar difficulty.

Knowledgeable in Statistics!
Peter was very helpful in tutoring me with expectational-maximization in theory and in R. He was prompt to respond, thorough in his explanation of the concepts, and patient and kind in his teaching methods. I highly recommend Peter!!
