Goodness-of-fit likelihood ratio statistics for age and of pr(insitu) effects in lesion surface area on tobit regression model for root-surface area: in each case the alternative hypothesis is the full model with age-dependent intercepts and pr(insitu) coefficients.
| Null Hypothesis | −2 Log-Likelihood Ratio | df | p-value |
|---|---|---|---|
| H0*: No age by pr(insitu) interaction | 3.70 | 3 | 0.295 |
| H0*: No age effect | 12.21 | 6 | 0.057 |
| H0*: No age or pr(insitu) effect | 166.5 | 7 | < 10−6 |
