### “Frequentism-as-model” — Andrew Gelman

Philosophy of statistics if you are into this. About ontology (reality) and epistemology (knowledge) of statistical modeling.

Statistical Modeling, Causal Inference, and Social Science

Probability Fact @ProbFact

Conditional probability is subtle. All probability is conditional. Therefore all probability is subtle.

PS: We just finished descriptive statistics. I think I'll save the introduction to probability for August. Would like my kid to start Clyde Pharr's Homeric Greek (the 4th edition edited by Paula Debnar) -- you know, just 30 mins, an hour tops, in the mornings :)

PPS: Remember that were it not for the Greek monks of the Middle Ages all the classical works would have been lost. It was they (sorry, not the Arab myth) that preserved the Greek writings the antiquity. So next time you're in Greece and you happen to come across a Greek monk, just say "Thank you" -- or "eucharisto." He'll understand ;)

Is it possible/likely/unlikely/impossible to have statistical models without assumptions?

@ lastgreek

The direction of development is PIE (lost) > Vedic Sanskrit & Avestan > Greek & Slavic Languages (Greek and Cyyllic are similar) > Latin (Roman)> Modern Indo-European vernaculars. The progression involves loss of structure. This list is greatly simplified. The important point linguistically is the degree of grammatical structure.

Knowing Greek is useful in looking back from it toward the origins, which are still speculative to a great degree, and forward to contermporary European languuages, a progression that is better known.

Getting kids interested in this stuff can be help in acquiring facility with language. This used to be necessary in being considered an educated person, but now the emphasis is on STEM. No reason not to be educated in both.

Objective and subjective are slippery concepts. Best displayed by the history of the terms, born in medieval philosophy. The original meaning of "objective" was today's "subjective", of "subjective" "objective". The reversal started a century or so after coining, and was completed by Kant. The original usage can be seen in phrases like "studying a subject in school". This "subject" is the "object" of your studies, and supposed to be something "objective" like chemistry.

The linked paper is good. They're coming to the standpoint of "absoluteness" of the German Idealists and their followers (British Idealists, some Marxists, some religious philosophers)- realization that they're inextricably linked, that one makes no sense without the other, that "the relation between subject and object is wholly dialectical". That "things as they really are, independent of observers" is an idea that makes no sense. Whatever you're talking about, you're the observer. The best you can do is talk about things as they are AND observers in a way useful to yourself and others.

As for writings from the ancient world. In addition, some came through Arabic. Some through Armenian. Some through wrappings of mummified cats in an Egyptian temple. Some might come soon through scanning of almost carbonized scrolls from Pompeii, too fragile to even open. I mean, the most valuable writings were written by smartypants Greeks in Greek- isn't who transmitted them secondary?

"No reason not to be educated in both."

yo, they work against each other:

https://psychology.stackexchange.com/questions/4538/is-abstract-knowledge-incompatible-with-literal-memorization

All the memorization required to do well in a Liberal education makes the student unfit for performing the abstraction required in STEM education...

You people should just STAY... THE... FUCK... OUT... OF... IT...

Let us who are properly trained handle it...

Go do your Art we STEM people actually enjoy your Art generally...

“ Let us who are properly trained handle it..”
Haha. No way I would let a hack like Matt handle anything.
