Does anyone know how to get an R-squared value for a fitted model using #lavaan in #Rstats? Specifically, I'm looking for R-squared for a regression model (i.e., one DV). I'm finding very little to work with online. I have a coauthor insisting that R2 is critical for his publication venue.

My original mech model (as in I designed it from scratch, there are some clear inspirations there), the Fantabulous Bruticus, is now available for download and print.
(If you print and paint, post a photo and tag me - I want to see!)

The geology of the ocean floor is truly spectacular — perhaps even more than land geology. Unfortunately, it's really hard to study.

“📉 KEY FINDINGS
• At +4 °C, only ~18,000 glaciers remain worldwide by 2100
• At +1.5 °C, ~100,000 glaciers survive
• [They] identif[ed] “Peak Glacier Extinction”:
– ~2041 at +1.5 °C (~2,000 glaciers lost per year)
– ~2055 at +4 °C (~4,000 glaciers lost per year)
🏔️ THE ALPS
• At +2.7 °C, only ~110 glaciers remain by 2100.
• At +4 °C, this drops to just ~20.
Can you imagine the Alps with almost no glaciers left?...”
