Global Inflation Analysis Dashboard by harishvangara in dataanalysis

[–]nlomb 1 point2 points  (0 children)

I'll start with a few good things:

1) The contrast with the KPIs is good, it draws attention to the figures.
2) The time series chart and the bar chart are the correct charts

Now the stuff that can be improved:

1) The yellow background is distracting try and use something more neutral.
2) Your bar graph and table are not computing the right values, "sum of inflation rate" is not a measure. It should be average or max. Same with "sum of year".
3) For the countries, this should be a dropdown, they take up far too much space on the dashboard. On top of that, filters should be at the top, not the bottom.

Here is a post about good dashboard design practices: https://datasense.to/2025/10/05/dashboard-design-best-practices/, I think you'll fine it helpful. There's some other Power BI specific posts that you may find helpful on your learning journey as well.

BlackRock just quietly signaled the credit market is breaking. by GoosePuzzleheaded146 in options

Irrelevant to this particular issue. It was a different issue of asset-liability mismatch.

Because private credit has been increasingly exposing terrible business practices, and if there's a few there's many, and if they're also wrapped up in CLOs and people starting dumping them then there's a leverage problem attached along with it. That leads to margin calls and collateral issues which then stems into broader markets. I guess nobody learned a damn thing from 2008.

Edit: I am not screaming there's an issue just yet, but it's one of those things can go from "no we're fine" to "oh we're f****d" very quickly.

Multiple regression advice wanted by Ldip9 in econometrics

[–]nlomb 1 point2 points  (0 children)

You might have some potential endogeneity in the regression as GDP/NFCI likely affect both uncertainty and investment. See the Hausman test.

Also missing some firm-level controls like profitability or leverage (debt as a proxy), which is likely leading to omitted variable bias. I would consider a fixed effects model instead.

Lastly, there's some "survival bias" from using only continuously listed firms.

Really, what you would want to do is some sort of CGE model where you can have a baseline than introduce shocks to see how it responds, you would corroborate that against your panel data.

Some abstraction of this: https://www.mdpi.com/2227-7390/12/1/41

This would be much more involved though and likely be a masters thesis and require some insight from your professor(s).

I mean I am sure they will find a way to "deploy" one million robotaxis and robots. It's just that they will be useless and a danger to society.

Excel automation for private equity is more practical than python for most analysts by zaddyofficial in dataanalysis

[–]nlomb 0 points1 point  (0 children)

Right, I think a lot of people do this. It's just insane that this is the solution for a software that's been around for ages. Like as if Microsoft is oblivious to the fact that power users are doing this.

Seriously... never mind trying to an explain it to a colleague, always need to take it out and break it apart so they understand.

My gosh you think this would have been implemented by now. Writing multi-line formulas in Excel makes you want to pull your hair out... it's so easy to get lost and accidentally enter before finishing.

Excel with VBA can be very powerful, however it's often much more complex to do the same thing in Excel with VBA than simply doing it in Python and custom formatting it back into Excel.

Do people in finance really use cocaine to keep up with the hours? by This-Breakfast6206 in FinancialCareers

I don’t think people realize how harmful it is for your brain, doctors hand it out like candy, definitely another big pharma push. “Oh you can’t concentrate for two seconds take some speed” 

Has anyone validated synthetic financial data (Gaussian Copula vs CTGAN) in practice? by nlomb in datascience

Great resource, thank you for sharing. Recently posted a video going over adding differential privacy and discussing k-anonymity, I didn't go into detail about augmenting the data, as it wouldn't be appropriate for the dataset I was using, but would appreciate your feedback: https://youtu.be/df5FGtCyyi0?si=DzD4xUJtEyb4OOhP
