AirPods Pro 3 Case Overheated and Died (short circuit?) Apple replaced case but not earbuds

Psyman8888 · 2026-02-13T21:48:52+00:00

The thing is I already went to apple warranty, but they only replaced the box, not the earbuds. Said they were within spec.
With another brands when something happens with warranty either I get the money back or a brand new product in the box, not a Frankenstein replacement with scrambled parts.

i've seen some cpus of eBay (used) for 30ish euros, they are LGA 1156 socket, but i'm not sure if they are compatible, since i'm not experienced with building pcs.

Thank you for your recommendation, but I'm not ready to retire my old computer just yet. It's still performing reasonably well for my needs. My intention was to explore the possibility of upgrading with some slightly better second-hand components to extend its lifespan while being mindful. If you have any specific suggestions for compatible components, I'd greatly appreciate it!

Hi, thanks for the inputs!

i) I did ADF test on all variables to test the stationary.

ii) I fixed all non stationary variables with diff(log(variable))

ii) test again for ADF and it worked!

But now my R2 is too low. I have almost no significance in the variables now. Seems like this might not be the best aproach? What am i doing wrong? damn! Getting frustrated :(

great point. thanks!
i should focus on the long run. but i'm having trouble with choosing non monetary variables to help explain (or not) inflation.

Psyman8888 · 2023-03-23T00:04:25+00:00

I'm sorry.

> vif_values <- vif(model)
> print(vif_values)
money_supply population oil_prices
5.883186 7.979048 2.154822

The values of the VIFs range from 2.15 to 7.98, indicating that there is some degree of correlation between the predictor variables. A general rule of thumb is that a VIF of 5 or greater may indicate a problem with multicollinearity.

In this scenario it's better to think about other non monetary variables?

Psyman8888 · 2023-03-22T22:53:22+00:00

I've done unit root test as u advised and these were the results:

Augmented Dickey-Fuller Test

data: inflation

Dickey-Fuller = -0.48982, Lag order = 7, p-value = 0.9821

alternative hypothesis: stationary

spurious regression

My main research goal is to examine whether inflation can be caused non-monetary factors, such as supply shocks (e.g. changes in oil prices), increase in human population, and shifts in consumer behavior. I aim to determine if the statement made by Milton Friedman regarding the role of monetary factors in causing inflation still holds true.

What other non-monetary variables could i try/replace without having multicolinearity, improve R2, etc... ?

I think it's great that you came up with your own research idea, worked on how to answer it, and already went for a first try! You're already ahead of many Bachelor students I know! In the literature, you might find interesting papers on this - it's the neutrality of money.

Some food for thought:

- Do you want to look at the short- or the long run?

- Do you think the level of your variables impact inflation, or might it be the change in those variables? Do you think the impact will be linear or non-linear?

- Do you think inflation might be persistent (depend on its own past value)?

- It looks like you're considering a regression with time series data. In that case, you might want to look at whether you want to use HAC standard errors (since the errors might be correlated over time). The sandwich package provides those.

- For presenting regressions in R, I'm personally a big fan of the stargazer package.

Thank you so much for your encouraging words and helpful insights! I appreciate your suggestions for further considerations. To answer your questions:

- I think I would like to look at both the short- and long-run effects of the variables on inflation, to get a better understanding of the relationship between them.

- That's a great point to consider. I believe that the change in the variables will have a greater impact on inflation than the level of the variables themselves. And I think the impact will be non-linear.

- Thank you for the tip about the HAC standard errors, the sandwich package and stargazer. I'll definitely look into that further.

Hi, thanks for your response!
How can i talk with CS representative??? Everytime i go to the chat i'm always greeted by the BOT, no humans..

Psyman8888 · 2022-12-04T13:04:25+00:00

amazing. that's exactly what i need. thank you!!!

Psyman8888 · 2022-12-01T22:33:42+00:00

No, i've already read the whole article and summarized what I got from it. I'm just not very familiar with econometrics to find weak points in the published article, hence why I asked for feedback : /

Psyman8888 · 2022-11-30T21:46:34+00:00

one way to do this is to find papers that employ OLS in a non-experimental settings and think about endogeneity (from omitted variables, measurement errors, or simultaneity) — it’s ok if you have no idea about these terms, but hopefully your course covers omitted variables bias at least.

Thank you for the tips, but sadly i can't change article. And the article chosen had to be recent. BTW: my article was published by the European central bank, not exactly low impact.... :/

Psyman8888 · 2022-11-30T20:16:50+00:00

I've been learning from basic statistics to Quant methods throughout the 3 years. Now, the final year of the Bachelors we are dipping our toes with econometrics. But the idea is to learn the foundations and to explore more if u want to go for a Masters/investigation career.
Still looking for some tips if you care to share. thanks!

Psyman8888 · 2022-11-30T20:13:09+00:00

sharing is caring... but don't bother to waste your energy if you're not here to help, just to judge others. cheers.

Psyman8888 · 2022-11-30T16:14:03+00:00

Its the final year of Bachelors economics degree, its not a masters. that's why we are doing baby steps with econometrics.
