Johnathan N.

Wonderful to work with.

It has been great working with Johnathan. He is flexible, knowledgeable and respects what you wish to get out of the lesson. Constantly he has gone above and beyond what is asked of him to help me out and adequately prepares lesson material before the lesson begins, which not all tutors do!

Highly recommended, R

Very knowledgeable in R! KNN algorithm. Emphasis was on creating factors, scaling data, extracting and storing variables, partitioning, one-hot-encoding (creating dummy variables), finding optimal K, creating a confusion matrix, and repeated cross-validation.

Great teacher, knowledgeable and patient!

What I appreciate the most about Jonathan is that he brings everything down to my level so I can understand what’s going. He understands I’m a beginner so keeps things as simple as possible. He used great examples to help me understand the “big picture”

Great Tutor very knowledgeable

Johnathan helped me with hypothesis testing questions. He explained the concepts and helped me use multiple methods to better understand and solve the problems. He is an excellent instructor.

Knowledgeable and freesharing

Johnathan is an extremely helpful tutor who is patient and successful in teaching because he is an expert in many domains. He is extremely well-prepared and does so before every session if you give him materials and time. I'm always amazed of the effort he puts in to teaching me and make sure I get the material and other questions if I have any. Very easy to connect to and very personable.

Fabulous and knowledgeable sessions

Jonathan has been so helpful with the various questions on R coding that I have thrown his way. I have an independent project that I am working on that he has helped me with for the past few weeks. Jonathan explains things clearly and simply and his code is straightforward and can work with many different applications. Generally, he is responsive and very flexible with his time. He also does not waste your time at all, making it efficient and cost-effective. I would recommend Jonathan to anyone looking to improve their coding skills.

Always a great help and very knowledgeable

Johnathan continues to be my tutor for R and statistical related course work since October. He is very knowledgeable, patient, and explains the theory and applications clearly. I will certainly be keeping Johnathan as my tutor as his breadth of experience and skillset is a great asset in discussing experimental and statistical design. My only regret is that I didn't seek him out sooner.

Great teacher, knowledgeable and patient!

As always, another great lesson in the books. I look forward to making progress and get better at programming R. I find it very helpful when Jonathan explains how a task can be done in different ways, using different functions.

Excellent tutor!

Jonathan was able to provide deeper understanding of my esoteric Bio-conductor program (including explaining the code underpinnings of how the program works) than I had expected. Highly recommend!

Easy going and knowledgeable

Jonathan helped understand the syntax of the R code I was working on. He also explained how different functions could be used depending on the size of the dataset. As an older adult, I appreciate his patience and style of teaching.
