#outliers — Public Fediverse posts

When I first heard "the plural of #anecdote is not #data," I thought it was very clever, and repeated it endlessly. So did, and do, a bunch of other people.

The original form of that saying was "the plural of anecdote is data." It was meant to urge researchers not to dismiss rare or unexpected results as #outliers. Both "the plural of anecdote is data" and "the plural of anecdote is not data" can be true, depending on context.

Like other #science aphorisms which have entered popular culture, particularly those containing the phrase "is not," this is a constant annoyance. I know my complaints won't make them go away. But I hope I can at least get people thinking about them, rather than parroting them and feeling smug.

Just something that came up tangentially today. Now, back to sorting out the anecdotes. Cells are wordy little bastards.

A quotation from Nassim Nicholas Taleb

Cumulative errors depend largely on the big surprises, the big opportunities. Not only do economic, financial, and political predictors miss them, but they are quite ashamed to say anything outlandish to their clients — and yet events, it turns out, are almost always outlandish.

Nassim Nicholas Taleb (b. 1960) Lebanese-American essayist, statistician, risk analyst, aphorist
The Black Swan, Part 2, ch. 10 “The Scandal of Prediction” (2007)

Outliers are common in data across various industries. This guide by Iván Palomares Carrascosa details strategies to handle them, from removal to transformation, using Python. Techniques include removing outliers based on z-scores, applying transformations like logarithmic scaling, and capping/winsorizing values. #DataScience #Outliers #Python #DataAnalysis https://www.kdnuggets.com/dealing-with-outliers-a-complete-guide

We the people species now classified
by the autonomous bots
as a rough approximation
of the standard median deviation
duly notated in the analytic bible
we are required to pray from

So our inevitable dissolution
will be an impersonal data execution
of a cold blooded algorithm
installed to maximize program efficiencies

Once we skewed variances have been classified
and human imperfections properly identified
a massive data dump will be launched
on all infected servers
to flush undesirable #outliers
replete with defective deficiencies
out of the now purified system

Glorious leader
has decreed
we the people
have forfeited
the antiquated right to dissent

No allowance for diversity
of unregulated opinions
in our contentment state
of mass conformity

The sheep simply must be flock obedient

So says the strict law of the land

Any deviation from the master plan
will be met with utmost violence

To those thought #outliers
who regrettably choose
not to participate
in the group program we demand
they will be forever damned
and sent to a mental hospital
for a permanent
attitude readjustment

RT by @EU_ScienceHub: "#AI always pushes out #outliers, which is anyone who’s not a white middle-aged man. So anyone in the audience right now who’s not a white middle-aged man is being treated #unfairly by AI systems.

That is the rule that we find when we #audit AI systems” - @gemmagaldon at #ESPAS

I was raised to think that I was responsible to assure that my #mother was happy. My poor #father likely suffered from #undiagnosed #PTSD from it

I bought into #lies about other #outliers in my family because I trusted her- I mean mom’s supposed to always be right and have our best interests at heart, right?🧐

Well, now that my #amnesia (et al) is at the stage it’s in, the only things I #remember about someone are my most recent experiences with them. How can she ( #abuse) possibly look to me?

Find the latest reported values with ease ✅

With the new #CrateDB v5.2, we've added two new aggregation functions: max_by and min_by 🧑🏼‍💻👩🏽‍💻

These functions simplify searching for the value of one column based on the minimum or maximum value of another column. They make it easy to #analyze #data #trends and identify #outliers 💪

Read the full #blogpost to learn how to use these functions in CrateDB 👉 https://crate.io/blog/find-the-latest-reported-values-with-ease.-introducing-max_by-and-min_by-aggregations-in-cratedb-5.2

Food for thought #Samples from higher #paleolatitudes were on average smaller, but contained #outliers with the largest #sizes, highlighting the need to analyze entire #distributions. #Lithology and #collection differences need to be accounted for when evaluating #size differences across #space (#polar #gigantism) and #time (#Lilliput #effect). Similarly, differences in #facies may affect #species #determination
