Great question. J (capital) was defined in an earlier video in the playlist. I wish I would have redefined it in this video. (little j) is define as j'=(1,1,...,1). J is a symmetric matrix of all ones defined as J=jj' Many thanks for watching. Don't forget to subscribe and let others know about this channel.

JY isn't defined at the 7 min mark should it be J'Y?
