| For cost estimators and analysts, the value of their portfolios can easily soar into billions of dollars. |
| Size change is so covariant among morphological traits in general that separate body parts are often good estimators of change in other parts. |
| The estimators are thus computed solving the linear equations obtained deriving equation for the unknowns. |
| Conversely, cost estimators are based on averages or generalizations that do not take into account the individual management abilities of a farm. |
| How can its estimators obtain pricing for the many items they are going to need? |
| As discussed above, they both have shortcoming as estimators of reliability. |
