For my second course, I am taking DTSC 650 Data Analytics in R. It’s the second course on utilizing the programming language R.
✍🏿 Here’s a description of the course:
Continuation of DTSC 550, with an emphasis on statistical techniques most used in modern data science. Will explore in greater depth linear and logistic regression, and continue to additional regression and classification techniques with a focus on application. Analyses will be completed in R.
This course will actually have two homework assignments I need to turn in, 6 exams, and a final project. Unlike the first course, which only had quizzes for a final grade.
The book we are using is free and located here. There’s a newer edition and I don’t understand why we’re not using it, but whatever. The book has lots of practice so far with great examples for the visualizations. I also like the exercise practice questions.
💡 Learning Objectives
- Use R to run and interpret simple linear regression
- Use R to run and interpret multiple regression
- Assess multiple regression model fit
- Describe multiple methods of multiple regression
💪🏿 This is what I accomplished my sixth week in the DTSC 650 course:
📺 Videos Watched (these videos follow along with the book):
- Regression Review
- Regression in Action
- Regression Interpretation
- Multiple Regression
- Standardized Regression Coefficients
- Multiple Regression Example
- Model Fit
- Methods of Regression Part 1
- Methods of Regression Part 2
- Calculating Multiple Regression Equation
💯 Exam
- An exam on Correlations with 12 questions. A few fill in the blank questions, multiple choice, and more than one answer questions.
- You can take the exam as many times as needed to get the score you want, but each test has different questions. I took the exam 2 times. Final score was 90.00%. You have until the end of the semester to take all your exams. I’ll see how I do when I start turning in graded assignments on if I need to retake any tests.
🔥 Summary
- Another easy week with just watching videos and a short test. Next week I have to submit my project and is my final week. I’ll talk more about it next week.
