The covariance matrix
What is a covariance matrix. In a nutshell it is a matrix that contains the covariances between levels of a factor in an ANOVA design.3 A covariance is the shared or overlapping variance between two things (sometimes called variance in common).

disagree  Daryo: In probability theory and statistics, covariance is a measure of how much two random variables change together. en.wikipedia.org/wiki/Covariance//Et alors? where do you "covariance" in this ST? How do you "avoid covariance"?????

to avoid overlapping variance with
pour éviter de mélanger les variations avec


Explanation:
when you amalgamate two statistical distributions, you get a statistical distribution that is made of two overlapping distributions, not as meaningful as the statistical distribution of only one characteristic.

disagree  Bertrand Leduc: ''Mélanger les variations'' ? c'est du langage mathématique ?
1 hr
  -> if "avoiding covariance" can make sense in statistics I must have skipped the classes about covariance...
disagree  Marcombes (X): variance n'est pas "variation"
16 hrs
  -> which is a proof that "avoiding covariance" makes sense? which bit of http://en.wikipedia.org/wiki/Covariance you think applies here?
