Polynomial Regression, R, and ggplot

Dr. Redmond was very thorough in the approach and taught the course very well. I enjoyed exploring how to code past what is typically used (overfitting a curve vs. parsimony).

Well taught. Easy to follow. Provides actionable takeaways. I would have liked to see a bit more theoretical depth in this course, especially for the part on smoothing splines.

This course is so good. the explanation, details provided, the data is also provided so that learners could perform along with the tutor. exceptionally good. Highly highly reccomend this.

One of the best I ever had as a beginner. The basics are extremely important to understand and this course give! Feel excited and motivated to continue!

This is my second course with Prof. Redmond, and I already wish that there were many more than just seven. The way he explains things is, as always, extremely clear and direct to the point.

Thats what experience is all about !! Share your knowledge. It’s a way to achieve immortality. Dalai Lama (1357 – 1419, high lama of Tibetan Buddhism) This proverb says it all . Keep on sharing .Thanks .

I appreciate the pace of learning and content is taught in a way that is easy to understand both practically and conceptually. Wish each course were longer and covered more material.

Excellent material put together in a brilliant way. If you´re looking for courses that go straight to the point, this is exactly what you should try out.

Durch die direkte praktische Umsetzung der eingeführten Konzepte an der R-Konsole und vor allem die dabei erstellten Visualisierungen vermittelt der Kurs statt lediglich abstrakter Ableitungen ein solides intuitives Verständnis der diskutierten Konzepte und zugleich das zu ihrer Anwendung in konkreten Analysen benötigte Handwerkszeug. Dem Dozenten gelingt es, miit wenigen kurzen Videos Theorie und Praxis einer komplexe Analysetechnik gut verständlich, so zu vermitteln, dass sie unmittelbar auf reale Datensätze angewendet werden kann. Der Kurs könnte m.E. davon profitieren, wenn dieser letzte Schritt, nämlich die Anwendung des Gelehrten auf einen realen, einen interessanten Sachverhalt abbildendes Datensatz noch in ein- bis zwei weiteren Videosequenzen vollzogen und so die Brücke zwischen Methode und Inhalt schlagen würde. Allerdings sollte jeder, der diesen wirklich sehr instruktiven Kurs absolviert hat, diesen letzten Schritt in dem ihm relevanten Sachgebiet auch selbst vollziehen können.

Free course and lecturer is very clear, taught at a good level for someone with a very basic grasp of R, someone with little knowledge of R would still find useful.

Another great (free) course from Charles Redmond! He has clearly brought his expertise from many years of teaching, as well as an excellent design of the coursework, to his Udemy courses.

The instructor was very clear and easy to follow. This is the second course in the series and as a total beginner to R I would not have been able to follow along had I not taken his first course beforehand.

Good class to understand how to use ggplot2 in conjunction with regression lines. As usual professor Redmond delivers the class in a clear and detailed manner to learn how to use R.

Teacher did not show how to save your own project,I was forced to recall all I do previous before start new lecture after some breake.

After having completed the Linear Regression course, i found this course to be an excellent extention to the first course. Looking forward to his next course.
