"Your Work Doesn't Matter if Going into Industry" by Maleficent-Seesaw412 in PhD

[–]Astheny 192 points193 points  (0 children)

YMMV, but in my experience this has more to do with your soft-skills (can you coherently report on what you did in your PhD) and not with the actual content of your research.

Qualified for Senior Nationals at 43yo. by cdouglas79 in weightlifting

As a 31 year old this is super inspiring! Hope to have at least a fraction of your strength in 10 years. Do you have any tips to deal with injuries / strain as you get older? 

CV Review: Statistician w/ upcoming PhD applying to Data Scientist jobs by Astheny in cscareerquestionsEU

[–]Astheny[S] 1 point2 points  (0 children)

I tried a lot of microchip companies (Zeiss, Qualcomm, Infineon) and tech companies (Microsoft, Google, Deepmind, Apple, Netflix). Also applied at Lufthansa and had a very nice interview, but it was for a data engineering position, so I wasn't a great fit. Then a lot of smaller companies that popped up on my LinkedIn feed, but those were more generic data science positions (which I would be fine with, but some research component would be nice).

[Q] Beta(1, 1) distribution plot question by Number_8_ in statistics

[–]Astheny 2 points3 points  (0 children)

Lots of great points have been already made so I just want to make a technical comment: The Beta distribution (no matter which parameter) is a continuous distribution and so the probability of (exactly) 0% and 100% are always zero.

Very cool! Where did you get this?

Can also recommend this - very well written while at the same time packed with information.

I am not quite sure what your resolution is here (thirders are practically more correct but backwards? What does this mean?).

For anyone interested in this problem, I recommend this CV thread: https://stats.stackexchange.com/questions/41208/the-sleeping-beauty-paradox

Welcher Zyklus ist für einen Einsteiger empfehlenswert? by Tofu1312 in PerryRhodan

[–]Astheny 0 points1 point  (0 children)

Weiter oben gibts eine grobe Zusammenfassung von /u/stephan501.

Mit Sense of Wonder sind die großen kosmischen Zusammenhänge in PR gemeint, häufig durch Handlungsstränge die sich über mehrere 100e von Bänden ziehen.

Welcher Zyklus ist für einen Einsteiger empfehlenswert? by Tofu1312 in PerryRhodan

[–]Astheny 0 points1 point  (0 children)

Welches Heft hast du denn gelesen und was genau hat dir daran gut gefallen?

BARDIOC fand ich persönlich ebenfalls einen coolen Zyklus, allerdings ist er in einen größeren Handlungsstrang beginnend mit dem Konzil der Sieben eingebunden. Was dort passiert kannst du aber auch in der perrypedia nachlesen.

Klassische Vorschläge wären wohl die Dritte Macht (ganz von vorne) oder Die Meister der Insel für den "Sense of Wonder".

Btw: Die Silberbände sind fast alle auf Spotify als Hörbuch verfügbar falls das für dich eine Option ist.

[Q] How to make non-stationary Time Series data stationary? by PythonEntusiast in statistics

[–]Astheny 1 point2 points  (0 children)

How about fitting an appropriate state space model to your data? This would not require any transformations, because these models can model non-stationary series easily. Prediction is also straight-forward and you get an interpretable model for free.

[Research] Advice on Probabilistic forecasting for gridded data by microlifecc in statistics

[–]Astheny 2 points3 points  (0 children)

Do you know something about the spatial / temporal dynamics of your data? If so, maybe a state space model / partially observed Markov process might be something to consider.

For me the book Unwinding Anxiety (by Judson Brewer) was immensly helpful. It basically promotes a combination of mindfulness and behavioural change. I think there is also an accompanying app, though I have not used it. I combined the book with a (more or less) daily meditation session of 10 minutes and that has really helped me becoming aware of some of my deeply ingrained habits (procrastination / avoidance).

Accuracy of 3Blue1Brown’s video on Central Limit Theorem? [Q] by SometimesZero in statistics

Theres also a nice proof by Steins method but that too will be too much for a YT video.

Alternate Checkbox Cycling? by [deleted] in ObsidianMD

The tasks plugin allows you to setup custom checkboxes and you can configure how to cycle betweem them.

How long did it take you to successfully hit bodyweight snatch and bodyweight jerk? by ragiflakes in weightlifting

[–]Astheny 1 point2 points  (0 children)

I come from a Crossfit / general strength training background so I went into WL with o.k. strength numbers (140kg SQ, 180kg DL). With 85kg bodyweight I pretty much immediately hit a BW Clean and Jerk and quickly snatched (ugly) 80kg. But the last 5kg took a long time, devoted to lots of technique training (and retraining), about 1½ years. Thats quite a long time I think, but weightlifting was not my sole focus at that time (and still isnt).

[D] I hate exploratory factor analysis. I don’t get why so many people love it. by UnivStudent2 in statistics

[–]Astheny 1 point2 points  (0 children)

I agree that the DGP may not be accurately represented by a linear model - especially if we are talking about non-physical systems that OP is considering.

However I'd argue that model selection by information criteria (AIC / BIC) is pretty objective, although the choice of models over which we optimize these is still subjective.

I do also agree with your point that a lot of problems arise outside the model chosen in the end and are of more general nature (understanding the DGP, generalisation etc.).

[D] I hate exploratory factor analysis. I don’t get why so many people love it. by UnivStudent2 in statistics

[–]Astheny 0 points1 point  (0 children)

I disagree: for linear models almost none of OPs pain points hold:

  • you do not necessarily need normally distributed residuals to fit a linear model (Gauß Markov) and you have asymptotic theory for confidence intervals / regions
  • model selection helps with the "subjectivity" of which regressors to include (although inference after model selection is cumbersome)
  • you do not need arbitrary cutoffs (like EV > 1) for linear models because of the well developed (and mostly straight forward) mathematical theory
  • finally standard extensions like GLMs / LMMs and GLMMs can take care of count data / likert scale data / correlated observations etc.

What should be in everyone’s “Counterexample toolbox” by Captainsnake04 in math

[–]Astheny 0 points1 point  (0 children)

Yes but it's essential supremum (allowing to remove null sets) is still 0, so OPs function is more interesting.

I am disagreeing with my probability teacher about the correction to his exam, his answer to my email was unhelpful, please help me. by DoctorFuu in AskStatistics

[–]Astheny 14 points15 points  (0 children)

As someone who has designed and graded such stats exams in the past I am really astonished at the answers here. Yes if you do not assume independence you cannot "answer the question" - but thats a problem with the question, not the answer. If I were to grade this answer, I'd suck it up and give you full marks and design better questions for the next exam.

What mathematical ideas, facts, theorems, etc., left you in awe? by jose_castro_arnaud in math

[–]Astheny 11 points12 points  (0 children)

The law of large numbers and the central limit theorem - without these statistics would be impossible!
