covariance formula statistics

Children who have studied probability statistics know that the most basic concept in statistics is the mean, variance, or standard deviation of a sample. First we give you a set of n samples, and then give the formula description of these concepts,

The key to understanding the covariance matrix is to keep in mind that it calculates the covariance between different dimensions, rather than between different samples, to get a sample matrix, the first thing we want to be clear is whether a row is

I sorted out several good blogs. Basic concepts of statistics Variance: Obviously, the mean value describes the intermediate point of the sample set. It tells us that the information is very limited, the standard deviation describes the average
