another definition video on our hands here least squares regression

00:28

What is it Why do we need it And well

00:30

who really cares Well some of us do believe anyway

00:33

this question just wants to know if we understand the

00:36

point of the least squares regression well we always want

00:40

the sum of the squares of the deviations to be

00:42

a small as possible so that the line describing that

00:45

data representatives is close to perfect as we can get

00:48

it least squares regression line is intended to do just

00:52

that to minimize the sum of the square deviations and

00:55

by doing so provide a best pit summary of the

00:57

relationship between our two variables It's something like a tailor

01:01

in that respect except it doesn't have to go around

01:03

measuring the deviations in scenes or so yeah this is

01:08

kind of one of those either you know or you

01:10

don't problems And in this case if you know it

01:12

you'll pick and through deep This is one of the

01:14

few times we fully endorsed regressing long as it's here 00:01:18.972 --> [endTime] and not in the playground
