I am trying to understand the meaning (geometrical) behind these two lines that I recently read in Wolfram (Geometric Correlation -- from Wolfram MathWorld)
A point-to-line and line-to-point transformation which transforms points into lines and lines into points such that passes through iff lies on .
Can anyone please help me understand this?
I know that there is a geometrical meaning to correlation (cosine of the angle between two vectors) but I wasn't aware of this point.
Thanks in advance
