This class has been extremely informative! I think the best part of this class is the fact that everything taught at a conceptual level was reinforced through practice. Every week there was an assignment due that encompassed the learning material covered in the lectures. This is the way to do it, especially when the conceptsContinue reading “Class Summary – Blog”

Week 14 – Blog
This week’s focus was mostly about logistic regression – which is super useful, and different than our typical linear regression model which focuses on continuous variable prediction. Logistic regression, on the other hand, falls under the binomial category – and predicts essentially a boolean value (either yes or no / 1 vs 0) In otherContinue reading “Week 14 – Blog”
Week 13 – Blog
This week’s lesson was all about text analytics. This was a really interesting and applicable lesson because most people can relate to social media and all the information that exists on the web (and in other various areas). Most of this information is in fact text, which illuminates the importance of this particular topic. RContinue reading “Week 13 – Blog”
Week 12 – Functions & Clusters
In this week’s lesson, we covered functions and clusters. Over the past few weeks, there have been several instances where we would copy and paste certain chunks of code and re-use them (modifying them slightly). By using functions, we can build our own code specifying the data, columns, and various other inputs to eliminate redundantlyContinue reading “Week 12 – Functions & Clusters”
Week 11 – regression
This week, our focus was on regression in R. We’ve been through regression before in SAS and excel, so conceptually, it was mostly review; but when we started to dive into the various capabilities in R such as plotting residuals, fitting the model, etc., we can see that R has more complexities here than SAS,Continue reading “Week 11 – regression”
Week 10 -Blog
This week, our focus was on manipulating data in R, that is using joins and other data wrangling techniques to combine and aggregate data in R. To date, this was the most time consuming assignment, mainly due to the the level of joining and aggregating we had to do for each step. However, during thisContinue reading “Week 10 -Blog”
Week 9 – Continuing R
This week, we really started to dive into R. R is a very powerful statistical analysis tool, and I think after exploring the intricacies of how it operates, I realized the complexities of what it can do. However, there were some real challenges (and still are some real challenges) to pivoting from SAS and ExcelContinue reading “Week 9 – Continuing R”
Reflection Blog – Week 8
This week, we focused on the midterm project, which covered everything we’ve done up until this point. The objective of this assignment was to take a large data set of property values and leverage other variables to build an optimal regression model. Our first task was all about structuring, exploring and transforming our data. TheContinue reading “Reflection Blog – Week 8”
Reflection Blog: Week 7
This week was really a review of everything we’ve learned so far. everything from proc import to proc reg and some of the more advanced regression procedures. In preparation for the midterm, the class used office hours to run through the techniques we would be required to use for the midterm – predicting housing prices.Continue reading “Reflection Blog: Week 7”
Week 6 Blog – Regression
This week, we shifted our focus to regression and prediction, as well as T-tests. We started the lessons with a quick review of all the past procedures we should be familiar with by now, including proc means, proc sort, proc freq, proc rank, proc sgplot, proc fastclus, datastep, etc. We then moved on to procContinue reading “Week 6 Blog – Regression”
