I would be very cautious in drawing any conclusions on the impact of GitHub use on student outcomes. This is a correlational study and correlation doesn’t imply causation. They dance around the issue by using “predict” in their report. A po

Not really. PCA extract components (or factors) using individual items (in this case, each stock). OP points out that those 4 stocks strongly load (large amount of their variation used to calculate the component) on the PCA first component.

We have used it to set up a small ML project. We decided to move away from it and to go back to Jupyter. We have found that file I/O is proprietary to Colab (e.g., the Google Drive interface). We had to rewrite that part of the noteboo

I think that the original synthetic control paper is this paper by Abadie and colleagues[1]. Figure 1 and 2 give you the intuition behind the need of using the a synthetic control rather than compare California to the rest of the US. You

The reference chain for the Namibia experiment is an Huffington post article[1] and a report by Bignam[2]. It looks like "Otjivero-Omitara was selected for its manageable size, accessibility, and poverty situation" (p.19). Ask you

Every time you want to evaluate results from social research, you need to ask yourself two questions: 1. Are the results internally valid? That is, did the authors reasonably control for factors other than the treatment (in this case, UBI)

I wonder how they got approval from the Northwestern Institutional Review Board. Not having explicit consent from research subjects might indicate that they qualified for some form of exempt status. Did they sell them that Dropbox collects

I would say try to get as much of the intuition behind the math as you can. Knowing what an equation means rather than fully understanding the Greek notation is what it matters for practice. If you want to substantially contribute to the th

To build on this a little bit more, there are also generalized linear models that allow to specify the reliability (i.e., error level) of a variable. Regarding, 2SLS models, I find them more useful to account for endogeneity in the model ra

It looks like they fit a (multinomial?) logistic regression. Unfortunately, the interpretation of the model coefficients is difficult because each coefficient is a log likelihood - therefore on a weird metric. I would suggest to look at the

The other important finding is the "negative externality" of laptop use on other people that are not using it. Even if someone is taking notes on paper and the student next to him/her is using a computer, research has found n

I am thinking it can help people that don't have a background in computer science but are tasked to analyze data (for example, a marketing manager for a company). Spreadsheet have a lower entry point (and a lower ceiling) than a regula

The education community has known for some time that there isn't a direct link between education spending and student achievement. That's because student achievement (as measured by international tests like PISA) is pretty much ju

ESSA just removes the federal requirements for proficiency levels set by NCLB (i.e., 100% of students will be proficient by 2011/2012 and all the safe harbor calculations that came with this mandate). ESSA, however, it stills requires

Up to 1999, most Italian Bachelor's were 4 years long (plus 5 years of high school). They were similar to current day US Master's degrees (17 years of total instruction). The current Italian model (adopted in 1999 with the Bologna

Nice idea! It looks that pythontex ( https://github.com/gpoore/pythontex ) is a more mature package. It seems it does not require to give shell permission to the script. It also supports syntax highlighting through pygtments and a python co
