Covariance Matrix is a measure of how much two random variables gets change together. It is actually used for computing the covariance in between every column of data matrix. The Covariance Matrix is also known as dispersion matrix and variance-covariance matrix. The covariance between two jointly distributed real-valued random variables X and

The mean signifies a central value for the data set. The variance of a data set measures how far the elements of that data set are spread out from the mean. Data sets in which the numbers are all close to the mean will have a low variance. Those sets in which the numbers are much higher or lower than the mean will have a high variance. 26/04/2010 · To calculate variance, start by calculating the mean, or average, of your sample. Then, subtract the mean from each data point, and square the differences. Next, add up all of the squared differences. Finally, divide the sum …
