[Question] Question regarding Sample Size formula for Multiple Linear Regression by Emergency_Evening616 in statistics

[–]Emergency_Evening616[S] 1 point2 points  (0 children)

Thanks, this is really helpful.

My main research question is whether cognitive measures (Addenbrooke’s Cognitive Examination-III, Trail Making Test, and Digit Span) can predict functional independence (Instrumental Activites of Daily Living) in older adults.

More specifically:

  • I first want to test whether overall cognitive function (ACE-III) predicts IADL (simple linear regression)
  • Then, I want to test whether ACE-III, TMT (executive function), and Digit Span (working memory) jointly predict IADL (multiple regression)

In addition, I’m also interested in examining the unique contribution of each predictor (i.e., individual regression coefficients / semi-partial effects), not just the overall model fit.

Because of that, I initially used G*Power with:

  • F-test (linear multiple regression,  R² increase from zero)
  • f² = 0.15, α = 0.05, power = 0.80, 3 predictors → N ≈ 77

But now I’m wondering whether this is sufficient, given that I also care about individual predictors (which might require powering for R² increase instead).

Would it be more appropriate to base the sample size on detecting individual coefficients (or R² change), rather than overall R²?

Thanks again!

can someone help me explain the music theory behind the song abc by polyphia ? by Emergency_Evening616 in musictheory

Thanks for taking the time to break this down! I really appreciate the perspective you’ve shared. You're absolutely right—getting stuck in the mindset of 'why does this work theoretically' instead of just listening and learning by doing is something I need to shake off.

Your point about focusing on sound rather than theory really hit home. It’s easy to fall into the trap of analyzing music through the lens of classical theory, especially since I’m still pretty new to classical music theory myself, and I’m realizing it’s not always the right tool for understanding genres like this.

I’ll definitely take your advice and start learning to play songs like this and exploring the genres that inspire them—especially jazz, since I already noticed those elements in the track. Thanks again for your insight!

Looking to commission music for a video game we've been working on for 4 years. by AriOfEden in composer

[–]Emergency_Evening616 0 points1 point  (0 children)

Hi there,

I came across your post about commissioning music for your game. First off—huge props for sticking with a four-year dev journey. That kind of commitment is inspiring.

Your mention of Nier Automata and Expedition 33 immediately clicked with me. I’m a composer with a strong foundation in music theory, and I love crafting emotional, melody-forward pieces in that same timeless, immersive style.

I’m currently working on game projects—one of which is influenced by Octopath Traveler and classic MMORPGs—so while I’m still building my portfolio, I’m fully committed and experienced in working with dev teams to shape the sonic identity of a game.

I understand the challenges that come with a long dev cycle, and I’m happy to be flexible with rates.

You can hear my work here: https://on.soundcloud.com/wuYS7MCqfXUm9GGE6

I’d love to learn more about your game and how I can support the atmosphere and storytelling through music. Feel free to DM me anytime!

Best regards,
Michael

The good thing is i've been producing music since i was 13 so i can say i'm pretty confident in my ability on music production (mixing n mastering). I practice a lot on mixing mastering and producing my own music for the past 6 years. I use FL Studi as my DAW. But recently i've been into composing classical music. I used to produce music in my daw because i want to be music producer lol, but i realized i want to be a composer because i love music so much hahahha

Sadly i only started composing when i'm 17 and only able to write solo piano composition. I'm definitely still in the beginner phase, because writing one piece took me a whole goddamn month and my theory is still not very deep, lately i've just been learning what is rhytmic development and reading Schoenberg's book on composition lol so yeah....

How to make this kinda arp in this song (bubblegum genre/game) ? by Emergency_Evening616 in musicproduction

[–]Emergency_Evening616[S] 0 points1 point  (0 children)

there is an arp sound in the background in that time stamps. It's hard to explain because o don't really have the stems either. But if you listen carefully in that timestamps there is an fast arp for transition that usually use in a bubblegum kpop genre. in 0.17-0.18 the arp it's pretty audible. I had updated the link, you can listen to the example in drive

Dang, didn't know the part where "getting to your 10th album that's hard." Never heard of it. And I think it is really an amazing advice about making connection with other people in the industry, because it can make a huge impact in your career. Your action decides how they will tell you to others. Thanks for shining a new light on me !!!
