Reporting

Note that neither t-values nor probability levels are given. The approximate statistical significance of a parameter estimate can be easily derived by eye by dividing the estimate by its standard error and comparing the result with t-values of 2, 2.6 or 3.3. These are the approximate t-values for P = 0.05, P = 0.01 and P = 0.001 levels of significance, respectively. Divide each parameter estimate in this table by its standard error and see what you conclude.
