How To Calculate Covariance Matrix : See full list on stattrek.com. For variance, in words, subtract each value from the dimension mean. , xnk x is an n x k matrix of raw scores: Suppose x is an n x k matrix holding ordered sets of raw data. We use the following formula to compute population covariance. We use the following formula to compute population variance.
Mathematically, it is the average squared deviation from the mean score. Where, n = number of scores in each set of data. Nov 03, 2017 · the covariance matrix for this data set is: Compute x'x, the k x k deviation sums of squares and cross products matrix for x. Xi is the ith raw score in the set of scores xi is the ith deviation score in the set of scores var(x) is the variance of all the scores in the set
