00:01
So we have two variables, y and x.
00:03
And we want to use x here to predict y.
00:10
So this means the x is our predictor here and y is our response variable.
00:22
So basically we can know like already which one is which.
00:28
So considering this, we know that, the 4 node that we should use to compute the intercept, so let's call the intercept b, is given by the correlation coefficient between these two variables.
00:41
And because we are using x to predict y, this means that we should put here.
00:47
The first one is for the y, the standard deviation from y, and then divide this by the standard deviation for x.
00:54
If it was the opposite, we are using y to predict x, we should change this deposition...
