| It needed variances because the building codes were set up for either residential or hotels, not both. |
| The demographic variances and covariances of the elements are inversely proportional to the total population size. |
| Also, it's unlikely that the reports are exactly the same. Subtle variances can make a difference. |
| As focus was on the cross-correlation modeling, quite simple structures for the variances and correlations of both variables were chosen. |
| Also, preliminary inspection showed no negative error variances and no theory-contradicting signs or magnitudes in the estimate values. |
| It shows that the genetic variances and covariances contributed by the additive and dominance effects cannot be fully controlled in the model. |
