Air is a public good and in any society with common sense, it should be a top government priority to provide clean air.

Alas, as we wait for that common sense to dawn on us, let's at least mask up in the meantime.

Survey of 416 residents. The polling group has a sampling error of 3% in their familiar territories. 95% Confidence Interval falls below 50%.

Yet the audacity/ignorance to claim that entire Greenland supports to be adopted by the US.

🏛️ Interesting argument on lack of democratic accountability 🏛️

1. It’s not the lack of awareness. But political partisanship is an obstacle to accountability.
2. Lack of social capital. Public support to policies that preserve public goods reduces if there is personal cost

I did. And correlated variables (without causation) are part of “deterministic” models.

Them not being “causes” didn’t stop them from being part of deterministic modes.

Because “to determine” is sometimes to decide something. And many correlations help in decisions, even if they’re not causes.

Cofounder causal diagram will become mediator causal diagram when we turn it.

Both variables will be needed to get the unbiased effect of the Mediator.

Mediator should be removed to get the unbiased effect of Confounder.

#Stats is absurd at times :p

Work with air quality or climate data? Here are a few ways to visualize them.

What other interesting visualisations can be made?

Adding on to discussion with @matloff.bsky.social

GLS requires estimation of the entire error covariance matrix.

To estimate these n*n terms using model residuals is not so easy.

We’ll have to make a lot of assumptions about the structure of the errors.
