If the columns of X have been autoscaled, then Equation (27) substitutes the correlation matrix of X (corr(X)) for cov(X). Autoscaling is a preprocessing technique wherein the columns of X are mean centered and then the variance in each column is normalized to unity by dividing each ...

Sample Statistics By convention, specific symbols represent certain sample statistics. For example, xrefers to a sample mean. srefers to the standard deviation of a sample. s2refers to the variance of a sample. prefers to the proportion of sample elements that have a particular attribute. ...

For example, in my colloquial way of using the word "average", the variance is the average of the squared deviation from the mean. Basically, in all my statements I am assuming (1) Kolmogorov axioms (2) relative frequency interpretation of probability, but that is even before quantum ...
