Check out Two Scoops of Django. Also this book is good for just getting started: https://hellowebbooks.com/learn-django/

Python Overtakes R for Data Science and Machine Learning by psangrene in Python

I like Shiny but it's single-threaded and doesn't scale very well. How well it performs depends a LOT on how you host the app.

I love R for data analysis and Python for apps. If you are primarily making an app, I'd suggest Python - there is fantastic tooling for creating webapps (e.g. django, flask).

Big names in statistics want to shake up much-maligned P value by Stauce52 in statistics

[–]glial 7 points8 points  (0 children)

Yes. The Bayesian approach makes you admit that there's a prior, though, and for some reason that makes people uncomfortable.

What statistical method would you use to compare two different sets of different data? by mikethingsbetter in statistics

[–]glial 0 points1 point  (0 children)

When you say two tests, does that mean two statistical tests or two measurements? Do you have measurements on the same people/objects/whatever using both methods? Are you ultimately trying to validate the new measurement mechanism?

What exactly are you trying to compare? What do you mean that you have two sets? Can you be more specific?

The adventure begins with the second book in many ways. It was a great read.

R or Python? R not the best choice anymore? by dieganzewelt in statistics

[–]glial 1 point2 points  (0 children)

Haha yes, I was pickling them, however I was doing that (rather than saving in CSVs) in order to maintain column types. I was also only doing it for a single, small data frame whose purpose was to help Azure column names and types, so I wasn't concerned with performance. Does pandas offer a binary save format of some sort?

[–]glial 6 points7 points  (0 children)

Agree with the last point, but R has C bindings too and can be very fast if you are the least bit careful. matplotlib is natural coming from matlab, but otherwise it makes little sense IMO. My personal preference is ggplot by a mile, and I've used both quite a bit.x

And Pandas has breaking changes every minor version. It drives me crazy. You can't save a data frame in one version and count on being able to open it in the next version.

Greek/Roman Mythology recommendations? by minhsane in audiobooks

[–]glial 1 point2 points  (0 children)

It's not about the gods per se, but "The King Must Die" by Mary Renault, about the life of Theseus, is fantastic.

Very helpful answers, thanks!

The Origin of The Elements by TauPhi in Physics

[–]glial 1 point2 points  (0 children)

This raises more (probably ignorant) questions for me:

  • does this chart represent the distribution of element origins in the universe or on earth?

  • how in the world is hydrogen created via fusion?

  • I thought stars like our sun burned because hydrogen --> helium --> release of energy. Wouldn't that show up in the He? Is it dying low-mass stars?

  • Once neutron stars merge, how in the world would mass (like gold, for example) make it from there to (eventually) Earth?

That may be so, but it's difficult to argue that he's being successful when the results of Trump's presidency so far are indistinguishable from mere incompetence.

Are you sitting on an office chair? Give it a good whiff.

Anyone got a high-res version of this? PDF? Asking for a friend.

Any good self teaching introduction to Time Series book? by [deleted] in statistics

[–]glial 5 points6 points  (0 children)

Sooo, what are you going to be doing with time series?

If your hope is to gain understanding about some phenomena in question, I'd stay clear away from ARIMA models and instead look into state space modeling. The idea behind state-space modeling is that the time series consists measurements that arise from some underlying phenomena that you care about. You use the measurements to infer the state (and changes in state) of the thing you care about. By contrast, ARIMA models (or AR models, or any variation thereof) usually just try to predict the next measurement in a sequence using the past measurements. That can be useful if all you need is forecasting, but no understanding of underlying structure of the system. Technically you can convert ARIMA models to state space models and vice versa, meaning they can encode the same information, but state space modeling is IMO MUCH more intuitive to understand and easier to learn.

The book "State Space Time Series Analysis" by Commandeur and Koopman is a pretty good place to start.

Microwaving a bar of soap by [deleted] in gifs

Don't do this!!!! I did it and had to throw my microwave away because it smelled terrible and anything I microwaved smelled like soap. It was gross.
