Quick Question: What is the design of this psychology study…

• repeated measures • IV – Condition 1, Condition 2, Condition 3. •DV – ‘accuracy’, ‘detail’, ‘verbosity’

In short, each person participates in Condition 1, Condition 2 and Condition 3 and for each is measured on accuracy, detail and verbosity; all of which are ordinal.

Is this a 3×3 repeated measures design?

Thanks all!

Help with controlling for gender in stata logistic regressions

How do I control for gender differences across logistic regressions in stata? I have been computing everything in a “Do-file” and would like to know if I can control for gender across all of the variables that I run in my Do-File? For example, if my DV is general misconduct and my IVs are age, race, etc. and my command looks like this “logit General_Misconduct v0005 RaceRecode” what can I do to look at how these variables impact misconduct and how it differs for males and females?

I was originally using SPSS for my thesis, but one of my committee members just suggested that I switch to stata and I have never used this before so any help/advice is greatly appreciated!!

What are current “hot” problems in math?

For the past weeks, I have been really fascinated by hard problems and theorems that took years, and even decades, to be proven. I was wondering, what problems are today’s best mathematicians trying hard to solve/prove, and what problems are looking like they are on the verge of being solved? Also, if those problems do get solved soon, what could that mean for the field of mathematics?

EDIT: What are some lesser known problems that are really important (read: not Millennium Problems)?

Career in Statistics

Hi, I’m currently an undergrad majoring in Statistics and I’m trying to get a good grip on all the career opportunities available to me with this major. I know that a lot of people nowadays try to get into Data Science, but I’ve heard that it’s very competitive now and almost always requires a graduate degree. Is this the case for most Statistics fields? What entry level options are there for people with a bachelor in stats?

Intuitions in Eigendecomposition, matrix rank and null space.

Could any stats gurus point me in the right direction?

I’m studying data science in grad school. I know how to compute matrix rank, null space, and perform eigen decomposition. I’ve read that that a matrix’s eigenvectors are fundamentally related to its null space.

I’ve tried reasoning this out but haven’t quite put it together. However, I feel that there is a BIG conceptual insight waiting for me.

If I’m approaching this the wrong way, I’d be grateful for that info just as well.

Statistical simulation and inference in the browser

Hi! I’m developing a free open-source app StatSim for statistical simulations, modeling and Bayesian inference. It includes more than 20 probability distributions, different inference algorithms (Markov Chain Monte Carlo, Hamiltonian MC, Rejection Sampling etc), various charts for result analysis. It’s 100% free, browser-side and doesn’t require registration. You can experiment with probabilistic models just to study or use data to find unknown parameters of your models. Comment here if you need help or found a bug. Feel free to share your models. Feedback is really welcomed!

Some examples:

https://statsim.com/app/?m=accumulator – Accumulator model

https://statsim.com/app/?m=pi – Pi estimation

https://statsim.com/app/?m=autoreg – Autoregressive model

You can also download Windows and Linux binaries for offline usage:
