Question

What do the coefficients of a linear regression tell you?

Answer 1

`b_(yx)` gives the expected value of y when x is independent and `b_(xy)` gives the expected value of x when y is independent, where `b_(yx)` and `b_(xy)` are the coefficients of linear regression.

Explanation:

r = `sqrt`{`b_(yx)` `xx` `b_(xy)` } is the Pearson's coefficient of correlation.
