Covariance of out-dyad values incident on each actor

This term adds one statistic equal to ∑_{i,j,k} y_{i,j}y_{i,k}/(n-2) . This can be viewed as a valued analog of the ostar(2) statistic.

# valued: nodeocovar(center, transform)

`center`	whether the y_{\cdot,\cdot} s are centered by their mean over the whole network before the calculation. Note that this makes the model non-local, but it may alleviate multimodailty.
`transform`	if `transform="sqrt"` , y_{\cdot,\cdot} s are repaced by their square roots before the calculation. This makes sense for counts in particular. If `center=TRUE` as well, they are centered by the mean of the square roots.

Note that this term replaces nodeosqrtcovar , which has been deprecated in favor of nodeocovar(transform="sqrt") .
