I am estimating an economic growth model that has 44 countries and 30 years, and in most of my estimation, I am using 3-year averages. I am getting confused when it comes to using xtabond2 in Stata.…

I figure this might be of interest to some. Under New Features for version 2.0.1 NEW FEATURES by longstanding request, lme4 now allows users to specify structured covariance matrices, by tagging the covariance term (e.g.…

This has probably been asked before, but I've been thinking about it a bit today and I wanted to see what you folks thought. A lot of introductory statistics courses usually set up one-sided z- and t-tests the following way: H0: mu = mu_0, H1: mu > mu_0…

Suppose you have two jobs available to you: A job that pays 40k/yr but allows you 100% free reign over whatever theoretical work you want to do, such as working on proofs for years on end that have seemingly no practical benefit.…

I applied a Bayesian hierarchical binomial model to ~800k MLB pitches (2020-2025) to assess whether Statcast's breaking ball taxonomy has discriminant validity. The short version: it doesn't, at least not between sliders and sweepers.…

How much guidance do PhD students get in a statistics or biostatistics PhD program? I want to learn how to do research (methodological and applied) and properly understand other people's research.…

I go to a T5 US college with 3.9 gpa but failed 2 courses (2 diff semesters consecutively) (It was on pass/fail tho so it doesn’t affect my gpa).…

I hear a lot of angst about the role of statisticians (especially junior statisticians) with the rise of AI. Having worked as faculty for a good bit; run an MS program; and engaged with various companies, I had a few thoughts that I think are maybe useful…

A bit of background: Imagine we have a sample S of 10000 participants from a larger, 40000 total population of individuals. For the 10000 sample we have some variables that we're interested in modeling, say the relation between height and diet.…

I completed my coursework for a double major in Data Science and Statistics earlier this month and during the final review of work completed the registrar informed me that I actually fulfilled the requirements to receive two separate diplomas and they are…

Hi guys, I recently graduated from UC Santa Barbara with a B.S. in Applied Mathematics, and I'm trying to decide between three Master's programs for this upcoming Fall 2026: Cal Poly Pomona - MS Statistics & Applied Mathematics (Statistics emphasis) CSU…

Hey all, I see some old posts discussing getting a Master's in Stats online, and which colleges are better than others. But I haven't seen a similar post about a Bachelor's. Which fully online Bachelor's would you recommend?…

I can’t seem to find a definitive answer to this. So, I thought I’d ask here. Is it ideal to include the elbow or not? I’m practicing some previous year question papers for an entrance exam and I came across this question: “If the plot shows a sharp drop…

Does having little to no coursework in your PhD disadvantage you in academia? Also, in Australia, you don't need a masters to enter the 3-4 year PhD, you do an honours year after your 3-year bachelor's degree, which is like a 4th year where you undertake…

I keep hearing about how anything that can be pipelined or has a sequential element to it will be automated. It seems most applied programs introduce tools where LLM’s are at the same level in terms of execution/production.…

I know I know that this is probably becoming a cliche at this point, but I just spent probably 30 minutes in the doomer hell that is r/jobs, and you’d think that everyone is on their last $10. It’s scary.…

Hello all, I am trying to analyse some measurements at work. 29 samples were tested and I wanted to see what the confidence intervals are. I put everything into Excel and used the Excel functions to calculate the different values.…

I'm currently pursuing a PhD, but I have only taken one statistics subject, so I would consider my statistical knowledge being basic. I want to compare multiple prototypes that accomplish the same task but differ in some aspects.…

Semantic discussion only - do you prefer referring to a long tail to the left as a left skew or negative skew? I won't bias the conversation with my opinion in the post. submitted by /u/slammaster [link] [comments]

[D] For example, American men are on average taller than Japanese men, so would American men on average have a larger standard deviation in height?…
