Hi,

I am trying to understand the meaning (geometrical) behind these two lines that I recently read in Wolfram (Geometric Correlation -- from Wolfram MathWorld)

Geometric Correlation:

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

Regards

Alex
