They halfdrowned him in a swimming pool.

I swam two pool lengths.

This is when I put active years in the regression equation by itself and I use the scale function and R to get the standardized regression coefficient.

Either way it's up to you.

The software will automatically give you.

It gets even easier if we want to look at the standardized regression coefficient.

Aspect of R that's a little bit unique. In most software packages if you run a regression analysis it will just.

And the reason we did that is so that we could see exactly how the regression coefficients are estimated in a multiple regression.

The school drains the pool once a month.

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

Hi, welcome back.

You've just won a Darwin award.

Just think of it as a little, round swimming pool.

The important concepts to take away from this segment are, again, understanding the equation and the components of the equation, how to interpret the, both the unstandardized and the standarized regression coefficients.

So again, minimize sums of squares residuals, just like in simple regression.

He was away from the swimming pool.

I want you to look at these black pools here.

Therefore, y will always be less extreme.

So, this term here.

What brought you back home?

Working alone. And.

And, in the last segment.

So, that's just the, the formula for a

It says rise over run, and if we want to do this just by hand, we could do it with this, simple formula.

And today we're going to do multiple regression analysis in R.

Than looking at either one alone. And, the other thing that this segment.

That minimizes J of theta one.

Now let's look at the simple regression with active years in the equation.

Come on, girls. sam, I need you to clean the pool tonight.

Down here big prediction error. For the rest of them, not so big, okay.

So, sometimes we use linear regression with tens or hundreds thousands of features, but if you use the vectorized implementation of linear regression, usually that will run much faster than if you had say your old for loop that was you know, updating theta 0 then theta 1 then theta 2 yourself.

And what we see is that both extroversion and diversity of life experiences both of those regression coefficients are significant.

Tom fell into the pool.

I don't want to go to the pool.
