Then we'll talk about the idea of estimation of regression coefficients.

Just like the sum of square, sum of deviation squares. So we'll square them.

Yeah, well, for the first two, we have names, addresses...

Again, there's variance in the population, sigma squared.

And that would give us the sum of squared residuals.

Look what's in the numerator, sum of cross products.

So, we wanna minimize the difference between the observed scores on Y and predicted scores on Y, predicted by the model.

X and Y, we are still assuming that X and Y are both continuous, both normal and there's a linear association between them and we will move beyond those assumptions

So the standard deviation is one half and the variance sigma squared would therefore be the square of 0.5 would be 0.25.

Now if I want to take this objective function and multiply it by 10, so here my minimization problem is minimum of u of 10, u minus 5 squared plus 10.

So we think of Ci as picking the cluster centroid with the smallest squared distance to my training example Xi.

How does R, or how if we want to calculat e this by hand, how do we come up with these estimates?

So if I look at my outcome measure Y, I can sort of parse the variants into two pieces.

59 squared, OK, and finally?

One third is less than one half.

2x squared.

The king's trip. Best cut there is.

With whole grain bread, you have other obstacles.

This is an interesting one where we seem to have a linear relationship that is flatter than the linear regression indicates, but there is one outlier.

So let me just graph those.

three minutes japanese sounds

So, we just know that look this side is equal to that side

We only have 1x squared terms, so let's write that down.

We'll write out the words Welcome to. We'll show Steven in bold.

You could say, well, this is just going to be equal to take the real part squared.

CV, and the second piece of this data, I'm going to call the cross validation set

It's getting blunter and blunter.

But of course minimizing squared distance, and minimizing distance that should give you the same value of Ci, but we usually put in the square there, just as the convention that people use for K means.

This is actually in my terminology one to three, but it just lists one two in this output.

First Delta

Last Delta

That's the second length of rope.

So let's see if they do that here.

OK, now we can simplify.

Lynn example.

I swapped the sides.

AB 23 squared, OK. Audience

When I say organized, it crosses over at a homologous point.

I missed the train by two minutes.

I'm gonna have time to live like a human being.

For a tall part, we can hold the recommended one third length with a taller jaw

Here is what I mean, to give you a concrete example, suppose I had a minimization problem that you know minimize over a real number u of u minus 5 squared, plus 1, right.

So we put in one density.

So again, 3 times 8 is 4, carry the 2, and so on.
