Quick Stata tip (ICYMI): keep if inlist(state, "AL", "AK", "AZ") is the same as: keep if state=="AL" | state=="AK" | state=="AZ" And: keep if inrange(distance, 10, 91) is the same as: keep if distance>=10 & distance<=91

Synthetic difference-in-differences, in Stata! Check out our article describing the package. Makes nice graphs illustrating time trends and unit weights. Comments welcome! arxiv.org/pdf/2301.11859…

A pro #StataTip for #reshape that I just rediscovered while fixing some code on the train: One can use the @ in reshape commands to indicate where the j-index is. This is especially useful if: (a) variable names r not consistent (fig 👇) (b) variable names have mutiple numbers

Quick Stata tip: to replace w/ "egen" commands, use "ereplace": *old way: sysuse auto2, clear *error: bys r: replace mpg = max(mpg) *instead: bys r: egen mpg2 = max(mpg) drop mpg rename mpg2 mpg *new way: ssc install ereplace sysuse auto2, clear bys r: ereplace mpg = max(mpg)

"War is persistent, but not prevalent." THIS (not "democratic peace") is the closest thing to an "empirical law" in international relations. How do we know it? [THREAD]

Quick Stata tip: use "geonear" to find the nearest point in B to each point in A: ssc inst geonear clear set ob 20 set se 1 g n2=_n g la2=39+5*rt(5) g lo2=-99+9*rt(5) tempfile a save `a' ren n2 n g la=la2+3*rt(3) g lo=lo2+4*rt(4) drop *2 geonear n la lo using `a', n(n2 la2 lo2)

One of my favorite papers in recent years included this diagram. It shows the impact of controlling for three different types of variables: confounders, colliders, and mediators. With confounders, control is good. With the others, you ruin your result by controlling.

My camera roll is now more screenshots than photos. Mainly things I want to eventually buy, places to go, stuff to remember etc. Feels like there could be a better way to traverse and map the internet?

Automated way of picking last 5 words in a string sentence using #Stata. Handy if desired text is difficult to extract using strpos(), substr(), etc. Code: github.com/fahad-mirza/pi… Can be modified to pick text from any part of sentence #data #DataAnalytics #string #datascience

Why, TEX, why?!

I’m excited to share American Stories, a new billion-scale dataset of structured texts/layouts from public domain newspapers (1780-1960) that we’ve built using our deep learning packages. #EconTwitter (1/13) Paper: arxiv.org/abs/2308.12477 Dataset: huggingface.co/datasets/dell-…

I wrote a Stata command that plots distributions of variables after absorbing variance from fixed effects (or controls variables). Here are examples. Read this thread for an introduction & motivation. github.com/leojahrens/fed…

Back after 6(!) years. Thanks for the warm hospitality and insightful suggestions! Delighted to reconnect with familiar faces and meet new ones. Always a great department, now even more so with fantastic new hires!

Quick Stata tip: I've written a book that compiles 97 of my Stata tips. You can download "Quick Stata Tips" and the companion .do file for free at toddrjones.com/quickstatatips/

Thanks for having me and for all the great suggestions! Johan Fourie Laboratory for the Economics of Africa's Past
