indexing question
...6]
I'm doing this because the above subractions represent pairs of returns
and the correlations between them wil be calculated eventually.
In other words, eventually I will have
X_36_31 ( i.e : temp[36] - temp[31] )
X_66-61
X_96-91
.
.
.
.
.
.
.
X_1411-1416
as one vector and
Y_41-36
Y_71-66
Y_101-96
.
.
.
.
.
Y_1416_1421
as another vector.
and will calculate the correlation between the two vectors in order to
get one number.
The point is I am really only using the indices 31, 61, 91 etc as
anchor's so a regular diff(temp[idx]) won't work because it will diff
all
the e...
