It is a synonym for error. It is the difference between the expected output and the output of our model:
Y - Ym
Where Ym is the output of our model. So residuals can be positive or negative and we need them to stay close to zero
How many times you have heard that your residuals should be independent, normally distributed with mean zero, and with constant variance?
No matter if your answer is zero or a million times. This thread can help you
It doesn't even matter that you don't know about residuals👇
It is a synonym for error. It is the difference between the expected output and the output of our model:
Y - Ym
Where Ym is the output of our model. So residuals can be positive or negative and we need them to stay close to zero
We don't want the error in for some input to be dependent on the error for another input
That would mean there is information about the relationship between inputs and outputs that our model is missing and that is present in the residuals2
Well, this is an intuitive one, isn't it?
We have said already that we need residuals close to zero. There should be both negative and positive residuals.
But we don't want a single huge positive error and then a lot of small negative ones
Let's continue
The mean of the residuals is zero, but that's not enough
We need about 50% of the errors to be negative and the other half to be positive
Also, we need most of the errors to be close to zero
In other words, we need the errors to be normally distributed
Last but not least. We need the errors to show a constant variance. This is a property called homoscedasticity 🥵
That means our model is equally good (or bad) for all inputs
Non-constant variance denotes our model is missing relevant information

"I lied about my basic beliefs in order to keep a prestigious job. Now that it will be zero-cost to me, I have a few things to say."
We know that elite institutions like the one Flier was in (partial) charge of rely on irrelevant status markers like private school education, whiteness, legacy, and ability to charm an old white guy at an interview.
Harvard's discriminatory policies are becoming increasingly well known, across the political spectrum (see, e.g., the recent lawsuit on discrimination against East Asian applications.)
It's refreshing to hear a senior administrator admits to personally opposing policies that attempt to remedy these basic flaws. These are flaws that harm his institution's ability to do cutting-edge research and to serve the public.
Harvard is being eclipsed by institutions that have different ideas about how to run a 21st Century institution. Stanford, for one; the UC system; the "public Ivys".
As a dean of a major academic institution, I could not have said this. But I will now. Requiring such statements in applications for appointments and promotions is an affront to academic freedom, and diminishes the true value of diversity, equity of inclusion by trivializing it. https://t.co/NfcI5VLODi

I'm going to do two history threads on Ethiopia, one on its ancient history, one on its modern story (1800 to today). 🇪🇹
I'll begin with the ancient history ... and it goes way back. Because modern humans - and before that, the ancestors of humans - almost certainly originated in Ethiopia. 🇪🇹 (sub-thread):
The first likely historical reference to Ethiopia is ancient Egyptian records of trade expeditions to the "Land of Punt" in search of gold, ebony, ivory, incense, and wild animals, starting in c 2500 BC 🇪🇹
Ethiopians themselves believe that the Queen of Sheba, who visited Israel's King Solomon in the Bible (c 950 BC), came from Ethiopia (not Yemen, as others believe). Here she is meeting Solomon in a stain-glassed window in Addis Ababa's Holy Trinity Church. 🇪🇹
References to the Queen of Sheba are everywhere in Ethiopia. The national airline's frequent flier miles are even called "ShebaMiles". 🇪🇹
