Heteroscedicity means error term with variance keeps on changing and autoregression means the present value is closely related to past state much like Markov chain.I dont this two are related

Sure Kurt, can you please confirm that this works in cloud based framework too.Can yu please share a /SASStoredProcess application with me, if you have one. Thanks.

I was just going through the article on the AUTOREG procedure and it mentions that auto regression and heteroscedasticity as similar . If it is similar then how is it also defined as time varying variance.

How is that a concern? I was trying to reiterate the fact that it was PCA and not DA. Can we come back to the original question now?Do you have an example to implement PCA using Kmeans? Thank you

I meant PCA using K-mean as both the algorithm are based on similar principals. I found it here http://http://epubs.siam.org/doi/pdf/10.1137/1.9781611972740.54. Thank you for sharing.
