What is the correlation coefficient is the geometric mean between the regression coefficient?

Let's regress $Y$ on $X$ and write $b_{0x} + b_{1x} x$ for the regression line, where $b_{1x}$ is the slope. Then Pearson correlation coefficient is $r = b_{1x} \frac{s_x}{s_y}$, $s_x$ and $s_y$ being the standard deviations of $X$ and $Y$, respectively. If, on the contrary, we regress $X$ on $Y$, the regression line is defined by $b_{0y} + b_{1y} y$, thus $r = b_{1y} \frac{s_y}{s_x}$.

Then it follows that $r^2 = b_{1x} b_{1y}$, i.e. $r = \sqrt{b_{1x} b_{1y}}$, which is the geometric mean of the two slopes.

What is the relationship between the correlation coefficient and the regression coefficient?

What is the difference between correlation and regression? The difference between these two statistical measurements is that correlation measures the degree of a relationship between two variables (x and y), whereas regression is how one variable affects another.

What is the correlation coefficient of two regression coefficient?

The correlation coefficient is equal to the geometric mean of two regression coefficients. The positive and negative sign of correlation coefficient depends on the sign of regression coefficients.

What is the geometric mean of two regression coefficient BXY and Byx?
