Simple Questions – September 06, 2019

This recurring thread will be for questions that might not warrant their own thread. We would like to see more conceptual-based questions posted in this thread, rather than “what is the answer to this problem?”. For example, here are some kinds of questions that we’d like to see in this thread: Can someone explain the concept of maпifolds to me? What are the applications of Represeпtation Theory? What’s a good starter book for Numerical Aпalysis? What can I do to prepare for college/grad school/getting a job? Including a brief description of your mathematical background and the context for your question can help others give you an appropriate answer. For example consider which subject your question is related to, or the things you already know or have tried. submitted by /u/AutoModerator [link] [comments]

Weekly /r/Statistics Discussion – What problems, research, or projects have you been working on? – July 24, 2019

Please use this thread to discuss whatever problems, projects, or research you have been working on lately. The purpose of this sticky is to help community members gain perspective and exposure to different domains and facets of Statistics that others are interested in. Hopefully, both seasoned veterans and newcomers will be able to walk away from these discussions satisfied, and intrigued to learn more. It’s difficult to lay ground rules around a discussion like this, so I ask you all to remember Reddit’s sitewide rules and the rules of our community. We are an inclusive community and will not tolerate derogatory comments towards other user’s sex, race, gender, politics, character, etc. Keep it professional. Downvote posts that contribute nothing or detract from the conversation. Do not downvote on the mere fact you disagree with the person. Use the report button liberally if you feel it needs moderator attention. Homework questions are (generally) not appropriate! That being said, I think at this point we can often discern between someone genuinely curious and making efforts to understand an exercise problem and a lazy student. We don’t want this thread filling up with a ton of homework questions, so please exhaust other avenues before posting here. I would suggest looking to /r/homeworkhelp, /r/AskStatistics, or CrossValidated first before posting here. Surveys and shameless self-promotion are not allowed! Consider this your only warning. Violating this rule may result in temporary or permanent ban. I look forward to reading and participating in these discussions and building a more active community! Please feel free to message me if you have any feedback, concerns, or complaints. Regards, /u/keepitsalty submitted by /u/AutoModerator [link] [comments]

Mod Announcement: Changes to Post Flairs

In an effort to better categorize discussion, we are moving to a system where users must flair their post in the title. If users do not specify a category, or specify a non-existing category, the post will be removed. We are working to allow abbreviations of flair requirements so the title is not encumbered by the post. The current supported flags are: Tag Abbreviation [Research] [R] [Software] [S] [Question] [Q] [Discussion] [D] [Education] [E] [Career] [C] [Meta] [M] For example, say you found a neat research article that you would like to share with the community. Your post would look like: [Research] Using Bayesian Methods to Improve Uncertainty Quantification in Computer Simulations or [R] Using Bayesian Methods to Improve Uncertainty Quantification in Computer Simulations We appreciate your patience as we add this information to the sidebar and posting guidelines. If you feel your post was removed in error, please feel free to message the mods. I’ve also setup a few more automod rules to try and catch click-bait post titles, political/off-topic posts, and troll-accounts. While these haven’t been such a big issue lately, I hope these new configs help reduce needless noise.

[R] The Rényi-type Statistic and End-of-Sample Change Point Detection (in R)

I wrote a blog post about the first research paper I’m getting published (with my advisor and his former student) on end-of-sample change point detection with the Rényi-type statistic, and its R implementation, along with change point testing in general. In the article I give a brief tutorial on change point testing problem and the well-known CUSUM statistic, along with an introduction to the Rényi-type statistic we developed. I explain issues in this type of testing, such as appropriate long-run variance estimation. I show the R implementations of these and other statistics (the Darling-Erdös statistic, the Hidalgo-Seo statistic, and Andrews’ test) in the new R package CPAT I wrote and demonstrate them both on artificial and real data. In the real data example I show how these tests can detect structural change in regression models by detecting changes in the alpha and beta parameters of Valeant Pharmaceuticals (VRX). I show that there was structural change, and that the new Rényi-type statistic would have detected a change in VRX’s alpha/beta sooner than other statistics (at least the CUSUM statistic). I provide in the article links to the original research papers, including the official JBES paper and the arXiv version. submitted by /u/NTGuardian [link] [comments]
