We will learn the covariance matrix is an nxn matrix (where n=number of data sets) such that the diagonal elements represents the variances of each data set and the off-diagonal elements represent the covariances between the data sets.

Perfect time for this Covariance series! My class is required to get an understanding of this for our Linear Regression machine learning algorithms. Thank you for these in depth videos on these topics. :D

Sir Michel has a good linear regression playlist too! I always recommend it when people wants to get in to machine learning

Dear Prof. Biezen, Thanks for the wonderful videos. Until previous video (4 of 17) , Sigma^2 was used for variance and here we have just Sigma. Kindly excuse me for being so pedantic.🙂

Yes, that can be a source of confusion, but that is the symbolism that is used in order to determine the covariance. Note the x and y subscripts (sigma x, sigma y) that do differentiate it from the normal variance symbold: sigma^2
