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.

I have started #writing backwards for my #PhD papers, and I have noticed a clear improvement in my sentence structure, grammar, and flow. I never thought about starting with the #conclusion, but now that I have, I am not going back — only backwards!

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.

2. Morning, it’s better to 𝐛𝐫𝐮𝐬𝐡 𝐚𝐟𝐭𝐞𝐫 𝐛𝐫𝐞𝐚𝐤𝐟𝐚𝐬𝐭.

When to brush your teeth? A good ANOVA study!
I found this paper which did a simple ANOVA study to find out when should one brush their teeth!

“Air quality data saves lives. Where air quality is reported, action is taken, and air quality improves.”

Oh I so wish 🌝

Depends on what we are doing with the data. A regression on it will optimise for global fit - thereby compromising predictions/inferences over the local imbalanced parts of the data.

🏛️ Interesting argument on lack of democratic accountability 🏛️

osf.io/preprints/os...

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

We wrote about gaps in monitoring data and its interpretation of air quality.

Stats gaps of representativeness, selection bias etc., creep into these datasets. Media, policy making should consider them before forming opinions.

If I ask you to forecast pollution in Delhi on some random day, you'd say a number X

If I further ask you to forecast on a Winter Day, you'd top up X with some y

This is Bayes theorem running in your head.

This blog attempts to quantify it

I wrote a book in Telugu where I addressed a few harmful beliefs (astrology, homeo, superstitions, biases) using basic stats concepts.

This blog of mine is one such attempt.

In a Gaussian distribution. An uninformative prior need not have any closed bounds.

So MLE would be identical to Bayesian estimate.

But give a closed bound (say mean height is uniformly distributed but within 100-200 cm) — Bayesian posterior estimates will consider this close bound — not MLE
