And that's true of any sample statistic.

So I can just rewrite that as A so now A is not a function anymore, it's just a number A times the second derivative of y, with respect to x, plus B times the first derivative, plus C times y.

When we look at ranking images, we know what the aspect ratio of an image is, how big is the image, how many pixels this image is.

Next I want to focus for a little while on the notion of a clustering coefficient.

This is supposed to be a constant

So there's a fair amount of interconnection between a node's neighbors.

So just getting it correct to a couple of digits is probably sufficient.

2nd derivative r squared.

Now it's about eighteen.

So we'd like to have a way of getting a pretty good answer in time a lot less than this.

The new images' size in pixels.

Okay, so hopefully you guess, correctly guess, that the answer is the second one, so namely that the number of

We'll come back to that again in multiple regression, and in lecture nine in R. And then, the importance of this distinction between unstandardi zed and standardized regression coefficients.

How strong is the relationship?

But again, now that we're in multiple regression, this is not the same as the correlation coefficient.

Largest to smallest has no predictable effect as the testing process is happening per pixel.

They're on the same side of the equation.

So let's multiply both sides by negative 3, right?

Let's just solve x squared minus x minus thirty is equal to zero.

I think you see what I did.

So please take care and free all of your wasted memory.

So, I just said and look, the a is just the coefficient on the x term, right? a is the coefficient on the x squared term. b is the coefficient on the x term, and c is the constant.

You literally just look at this coefficient right here, and you say, OK, well what's half of that coefficient?

When we complete the square, we just take half of this coefficient.

Low error factor

And let's see whether this is equal to 0.

So a plus b will be equal to the middle coefficient.

We have x of 1, 2, and 3 and y of 4, 7, and 13.

When you, do the simple regression equations.

So the important topics to take away from this segment.

And then, we can have multiple predictors and multiple regression coefficients.
