Who is using regression models with interactions?

Started this discussion. Last reply by Andrew Reid Mar 15. 2 Replies

I believe biostatisticians use it, especially with small data sets, in the context of clinical trials, especially when using dummy variables (e.g. 0/1 for gender.) I am wondering how decision trees…Continue

AI: Miniaturization of Robots

Started this discussion. Last reply by Michael Rawson May 18, 2018. 2 Replies

Maybe this seems like science fiction, but I was wondering if some companies are developing robots that are so small, that they are about the size of a virus. You could imagine a swarm of robotic…Continue

Is it better to overpredict, or underpredict?

Started this discussion. Last reply by Ethan Scott Mar 14, 2018. 5 Replies

Weather predictions are notoriously difficult for the Seattle area. I have seen many instances in which snow was predicted (say 1 to 3 inches) while the actual amount was much smaller. I assume that…Continue

"Agree, this sort of representation doesn't help as a data visualization. I wouldn't "compare values ... with a nice picture" at all. First, a pair of pictures like this and the details on them (esp. on the bigger one) distract…"

Andrew Reid replied to Capri Granville's discussion Who is using regression models with interactions?
"Hi Capri, Forgive me if I've got the 'wrong-end-of-the-stick' here but I am always cautious about using categorical variables (especially those with few 'categories') in interactive effects. In the illustration used here, it…"

John Williams replied to Capri Granville's discussion Who is still using regression models with interactions?
"Is this a question or a statement? The title of the article seems to imply that modelling interactions is passé, but the text of the article seems to advocate doing it. So I'm a little confused. If it's a question, then the answer…"

How the Brain Interprets Visualizations

I was comparing home prices in San Francisco between 1994 and 2018, and I noticed that it has increased by a factor 4 over 25 years. In the meanwhile, the inflation index increased by a factor 1.7 (see here.) I am not saying here that my sources are correct or wrong -- entire books have been written on the subject -- but instead, my purpose here is to show how some visualizations can be…See More

I believe biostatisticians use it, especially with small data sets, in the context of clinical trials, especially when using dummy variables (e.g. 0/1 for gender.) I am wondering how decision trees and other models compare with interaction regression. I would think the interaction regression  model suffers from the same issues as polynomial…See More

Machine Learning, Deep Learning, and AI Terminology for the Layman

Posted on February 27, 2019 at 3:30pm 0 Comments

Here is one of the most viral videos about data science posted in the last few months, with over 500,000 views. I could not locate the original copy; I found it in a re-tweet by Kirk Borne. See link to the video below the picture. However, I was able to find who created it (Welcome.ai) and it turns out that they have a YouTube channel with plenty of even more interesting videos. To search these videos by keyword, click…

Question: A researcher is interested in actual data to research in patterns and build a model for prediction. My question is that if a researcher is interested in actual data why we transform data?
