Derive the mathematical relationship between correlation and Euclidean distance when each data point has been been standardized by subtract- ing its mean and dividing by its standard deviation.
Here, we further explore the cosine and correlation measures.
Let x and y be two vectors where each vector has an a mean of 0
and a standard deviation of 1. For such vectors, the variance (standard
deviation squared) is just n times the sum of its squared attribute values
and the correlation between the two vectors is their dot product divided
by n.
