“changes in statistical significance are often not themselves statistically significant. … even large changes in significance levels can correspond to small, nonsignificant changes in the underlying quantities.”

The Difference Between “Significant” and “Not Significant” is not Itself Statistically Significant

It is common to summarize statistical comparisons by declarations of statistical significance or nonsignificance. Here we discuss one problem with such declarations, namely that changes in statisti...

Besides mediation mess, they never test if the diff between significant in females but not significant in males are significantly different (cf. Gelman & Stern) or why.
No sex diff in MDD vs not gps is odd as expect 2:1 for MDD.

"So, are you illuminating a mediation structure, assuming a mediation structure, or testing for a mediation structure?"

"Yes"

"Thus, mediation effects are valuable not because of their size, but because they can illuminate causal structure, inform further research on targeted interventions, and accumulate meaningfully across systems and populations."

"we investigated whether the data are compatible with a model in which Eggerthella abundance mediates the association between soft drink consumption and MDD diagnosis in women."

"To test whether the effect of soft drink consumption on MDD diagnosis and symptom severity, respectively, was mediated by the gut microbiome, we used a mediation analysis with soft drink consumption as the predictor, Eggethella and Hungatella, respectively, as the mediator,"

Mini IRT rant: Why not name the slope/discrimination parm. b since b is usually slope? Then a could be difficulty, which makes more sense because 1PLM only difficulty parm. varies, so it should be 1st letter of alphabet rather than 2nd. Then models & labels align: 1PLM a, 2PLM ab, 3PLM abc.

Jill A. Jacobson @doctorjaj.bsky.social · 3d

ICC = intraclass correlation coefficient or item characteristic curve.
a = y-intercept, slope or discrimination parameter, path from IV->Med
b = slope or regression coefficient, location or difficulty parameter, path from Med->DV
c = guessing parameter, total effect, with a ‘ direct effect

I feel like psychometrics is uniquely bad at naming things. Parallel, congeneric, tau-equivalent, essentially tau-equivalent measures? Configural, metric, scalar, residual invariance? Item difficulty defined so that the higher the difficulty, the easier the item???

Newest LLM tell/quirk in coding assignments this semester: instead of generating code based on the CSVs that I provide, LLMs have been inventing datasets with rnorm() and sample() (and an obligatory set.seed(42)) and then making plots with the fake data.

I'm so tired.

I love seeing things like this when you can tell the original author of the scale was obviously annoyed about his scales being used in ways that he did not intend...and also by the emails.
And I love that Carver's department let him leave these notes on the website.
