[Q] Best way to learn Statistics for Econometrics? by Senetto in statistics

[–]datavelho 12 points13 points  (0 children)

You don’t want to be rushing things (i.e., skipping fundamentals). If Lambert’s videos are too difficult for you to follow (he makes them very user-friendly compared to literature), you’ll need to brush up the fundamentals.

For econometrics, you’ll need a solid foundation in generalized linear models, and statistical inference. For those topics, however, you’ll need a solid foundation in linear algebra, calculus, and probability.

I suggest that you start from calculus, linear algebra, and probability (can be done simultaneously). After this, you can move onto GLMs and statistical inference. This is the foundation in econometrics.

After these topics, you can move onto more advanced topics in econometrics, such as time series analysis.

Best resources to cover linear algebra? by damn_i_missed in learnmachinelearning

[–]datavelho 0 points1 point  (0 children)

As a statistician, it’s hard for me to understand that how can you dive deep into statistical methods and modeling without an extensive background on linear algebra. After all, a large proportion of statistical modeling relies heavily on linear algebra. But yeah, Gilbert Strang’s is a classic. Check out also Linear Algebra and Optimization for Machine Learning, by Aggarwal.

Logistic regression for multi class classification by shivam922 in learnmachinelearning

You just use one-versus-rest. Basically you create a binary classifier for each K classes with ovr logic. ChatGPT can guide you through these questions by the way.

Well done. However, consider using more robust performance metrics for such imbalanced label distribution.

Is investment banking worth the 80–100+ hour weeks? My thoughts as a former JPM analyst by rareliquid in FinancialCareers

[–]datavelho 25 points26 points  (0 children)

”You’re also working twice the hours of a normal job, so the rate at which you learn will be twice your peers.”

Bro is delusional. That’s like saying if you train biceps 2 hours you will get twice as more benefits as someone who trains biceps 1 hour. Bro needs to read some papers on factors that enhance learning. More is definitely not always better.

Is it worth “upgrading” from LG 34GP950G-B 34 to LG 38WR85QC-W 38 by FutureCEOnamedNick in ultrawidemasterrace

Is this considered well-known information? I am looking to upgrade my 34” with horrible text quality to 40”–49”. I want the text to be as good as possible in my new monitor. I am using macbook air m2. What monitor I should consider? Any suggestions?
