Interactive resources With the power of OJS and Quarto, I’ve created a few interactive websites to illustrate trickier statistical concepts when teaching. Check them out (and adapt and copy as much as you want!) With links to three different websites (accessible at the main link in the post)

Finally got around to adding fancy links to my different interactive teaching websites for showing things like p-hacking, p-value interpretations, and (still-in-draft-form) DAGs at www.andrewheiss.com/teaching/ #rstats #QuartoPub #statsky

There is a tsunami of fake social science research coming for us, and the American Sociological Association doesn’t care There are so many red flags that this system is sending up, crying out for the scholarly research enterprise to defend itself. Sadly, reader, that does not appear to be happening.

I wrote it up here, with a picture of a mockingbird, and links to data and code.

I ran a simple model with new public data then used 1 prompt to make ChatGPT guess what the model would produce. With 10 seconds of "thinking," it was very close. The implications of this are catastrophic. The American Sociological Association should do something about this but it doesn't care to

Where is the DAG? 😂

In case of informative censoring due to migration out of the pop at risk, I use a competing risk model. The migration is competing with (=not independent from) your diagnosis event. More difficult to deal with people returning (after a gap): you may not know if they were diagnosed elsewhere.

Gen Z men twice as likely as baby boomers to believe wives should obey husbands Global survey shows young men hold more traditional views about gender roles than older generations Almost a third of generation Z men think a wife should obey her husband, according to a global survey of 23,000 people that found young men hold more traditional views about gender roles than older generations. A third (33%) of gen Z men also said a husband should have the final word on important decisions, according to the 29-country survey which included Great Britain, the US, Brazil, Australia and India. Almost a quarter (24%) of gen Z men think women should not appear too independent or self-sufficient, compared with 12% of baby boomer men. Attitudes toward sexual norms also differed sharply across generations, with 21% of gen Z men thinking a “real woman” should never initiate sex, compared with only 7% of baby boomer men. More than half (59%) of gen Z men said men were expected to do too much to support equality, compared with 45% of baby boomer men. For women, the proportions were 41% and 30% respectively. Thirty percent of gen Z men believed men should not say “I love you” to their friends, compared with 20% of baby boomer men and 21% of gen Z women. Twenty-one percent of gen Z men believed that men who took part in caregiving for children were less masculine than those who did not, compared with 8% of baby boomer men and 14% of gen Z women. Both genders felt women had more choice in dating and relationships (22%), household roles (24%) and the clothes they can wear (34%), while men were considered to have more choice in hobbies (18%) and jobs (39%).

Weaponizing Kinship: Four out of ten Colombians have lost a family member in the conflict 🇨🇴

Regression to the mean 😜🤣

Results are, epectedly, that "Countries with lower wealth and research allocation in GDP are less researched despite having larger immigration and emigration stocks."

Decolonising migration analysis? Still a long way to go.

New estimates of education-specific fertility show significant variation across 36 Sub-Saharan countries, with divergent fertility trends. The new flexible model demonstrates differences between UN and Demographic and Health Surveys data. www.demographic-research.org/articles/vol...

With some help from Claude Code, I have the app I've always wanted:

elicitcausal lets you design a causal graph with your theoretical priors & preregister it. Then after you complete a study, you can upload your graph and get estimates of causal learning.

#USA vs #EU power struggles over #data and #GDPR

Urban areas might increase out of natural growth, urban sprawl and reclassification, but not because of net migration from rural areas. But yes, it still involves a lot building.
