Covariance method only for Alea instances
Issue #57
resolved
The cov
method is only available on Alea instances, i.e. independent random variables.
This makes its usage quite limited:
a.cov(b)
- raises exception if
a
is not an Alea instance, - =
a.var
ifa is b
, - =
0
ifa is not b
andb
does not refer toa
, - = a non-trivial covariance in other cases.
a.cov(b)
should work on any Lea instances.
