Data Provenance: What Solutions Are You Using, If Any?

Hello everyone,

I’m curious about how people in this community are handling data provenance. For those unfamiliar, data provenance is about tracking the origins and transformations of data throughout its lifecycle.

Are you currently using any tools or methods to track the provenance of your datasets? If yes, what solutions are you using? Are they custom-built or off-the-shelf? If not, do you see a need for such tools in your work? What features would you consider essential in a data provenance solution?

Retail Electricity Prices In PJM And ISO-NE Operation Regions

I am trying to decompose retail electricity prices into its components (transmission costs, fuel costs etc), and discuss determinants of retail energy prices in these two markets. My overarching goal is to explain the reason(s) behind different energy costs faced by retail customers across the US. These two regions have the most similar markets among those with organized capacity markets (although correct me if I am wrong). These regions have consistently high pricing, but what explains this discrepancy compared to the rest of the country? Locational Marginal Prices would also work.

Any advice is greatly appreciated. Thanks in advance!

Final Year Project In Data Analytics

Hi all,

I am currently a Malaysian student, in my final year and have my FYP pending. I am studying computer science, specialising in Data Analytics. I’ll need to do the standard data pre-processing, visualising, model building etc. However, it is mandatory to include 1 of the SDG goals in my overall project.

I just need some advice on which potential topics I could go into, as I keep over thinking every topic, and am struggling to settle with one. And if anyone could help me find some good datasets to go with the topic, that would be very appreciated.

Thanks to anyone who takes time to read this!

Looking For Owner-occupied Housing By ZIP Code (USA)

I’ve been searching for a reliable data set showing owner-occupied housing numbers by ZIP code in the US. I’ve found several data sets from HUD and the Census Bureau, but so far I’ve not found these numbers, at least broken down by ZIP code. Has anyone else found a reliable source for such data? Thanks in advance.

Has Anyone Used The Health And Retirement Study 2016

I was doing a project using the Health and Retirement Study (HRS) but it turns out the years I wanted to use would not work but 2016 would. The data is downloading as a .dat file which means that it is not possible to open. Has anyone ever used it in the past before it was converted to a .dat file. I need to make this change in 24 hours and have spent the last few months trying to clean the other data I thought I needed. Now I need to make this switch.

Looking For Datasets On The May 6, 2010 Flash Crash

Hi everyone!

I’m a student working on a research project about the 2010 Flash Crash. My focus is on understanding how algorithmic trading and market infrastructure contributed to the event.

I’m searching for historical datasets that capture intraday trading activity on May 6, 2010, particularly for key indices (Dow Jones Industrial Average, S&P 500, and Nasdaq Composite Index) and other heavily impacted individual equities. Ideally, i’m looking for tick-level or minute-by-minute data, but i’m open to aggregated datasets as well.

Also any pointers to how I can obtain this data is appreciated!

Thanks in advance!

Weight And Height Of People In One Country Over Time

People used to be small. And now they are taller and have a heavier BMI. But i wonder what the increase of just weight (mass) over time looks like. Theres data for BMI in ourworldindata and gapminder. But not raw
average mass eg of men in France 1900 60kg, 1920 65kg 1940 70kg etc type data.
The separated out heights and weights that make up BMI.

Do you know a dataset like this?
This wikipedia page links to individual government sites but searching for German data if you are not german is really hard https://en.wikipedia.org/wiki/Human_body_weight

BMI but not height and weight separated https://w3.unece.org/PXWeb2015/pxweb/en/STAT/STAT__30-GE__06-Health/006_en_GEHEWeight_r.px/table/tableViewLayout1/

https://www.gapminder.org/fw/world-health-chart/
Heght and weight but not with by historical time https://www.kaggle.com/datasets/burnoutminer/heights-and-weights-dataset
3 recent years but not a long view https://data.gov.ie/dataset/his53-average-weight
Does the us army have data on the people it takes in each year? That would do it.

Working With Vectors Of Data, Building Intuition On Disparate Data Sources

If I have two vectors:

exam scores [100, 80, 90] exam weights [.4, .3, .3]

I can take the dot product of these two and find *i’*s total score. Now across many rows, I can find “the class” total scores by i.

Now, imagine I have two other random vectors:

happiness score [10, 8. 9] sadness score [10, 8, 8]

Mathematically, nothing is stopping me from taking the dot product of happiness score and sadness score for person i.

This is where my intuition isn’t strong. What “possibly” could the dot product of these two mood scores tell me? I am just looking for any random ideas or ways to take the dot product and “make it make sense”.

Overall, This will help me take different vectors of data sets and infer insights. So, if you are given two vectors, how do you approach “combining them” to product an output that “makes sense”?

Help Regarding NIS Database Research Analysis

I’m fairly inexperienced with programming/data analysis and I’m unsure of how to proceed with my dataset. Hopefully I’m posting in the correct subreddit.

I’m using a national inpatient hospital database (NIS database) to analyze at how a specific procedure volume changed pre vs. post COVID. I’ve already combined the years I’m looking at (2018-2021), filtered the data for only the procedure code I’m interested in, introduced a time period variable (2018/2019 =1, 2020/2020 =2) and weighed my cases by the “discharge weight” variable to represent population estimates. At this point, each row is basically a count for the procedure.

Now I’m stuck and don’t know what kind of statistical analysis I should be doing and what variables to use. I’ve played around with using independent t test using time period x discharge weights, thinking that each row x discharge weight = estimate of procedures, but I’m not really sure if that’s right.

I’d appreciate it if someone could please help me with this.

Looking For 3D Successful Prints Dataset Sources

Hello guys! We have a thesis proposal entitled: YOLOv10s in anomaly detection and classification in 3D Printing. Since we want to train our model for both images of 3d prints with defects and without defects, we already have dataset source for 3D Prints that have defects but we are having a problem with finding dataset for the one without defect or 3D prints that are successful. Anyone has the idea where we can look sources that has those images, if possible with annotations already. We already looked all throughout Kaggle and Roboflow. Thank you in advance!!
