Anthony,
I now can't afford to forget that R is case-sensitive!

b) This is a statistical question but, for instance, in the case of

No need for a loop. "else if" doesn't exist in R. And Health2$CohenM and

and "-". And I would suggest to not add new variables in your data

Dear All,
is there a function in R that would help me convert a covariance matrix built
based on arithmetic returns to a covariance matrix from log-returns?
As an example of the means and covariance from arithmetic:

sigma

B=A[1,,]
dim(B)
