Regression analysis of age and sex standardised mortality in Japanese prefectures (n=47)
| Predictors | Male | Mortality | Female | Mortality |
| 1 | 2 | 1 | 2 | |
| Income p/c | −0.16 | 0.12 | 0.26 | 0.521-150 |
| Physicians per 100 000 | 0.14 | 0.00 | −0.11 | −0.24 |
| Industrial area | 0.511-150 | 0.491-150 | ||
| r 2 | 0.02 | 0.14 | 0.06 | 0.17 |
Numbers are standardised regression coefficients.
↵1-150 = Significant at the 0.05 level or better. Standard errors are dropped because this is the universe and because it is the shifts in the strength of the coefficients that are paramount.
