This variable was modelled on a logarithmic scale for the lung condemnation model in order to linearize the relationship with the outcome.
The video, showing people mocking the plight of Grenfell victims as the cardboard model burned, drew condemnation from survivors of the deadly blaze last year, as well as the prime minister, Theresa May, and the chairman of the public inquiry into the disaster, Sir Martin MartinBick.
The unrated abattoirs were unlikely to have influenced the model since the condemnation rates for abattoirs in this category were not significantly different from abattoirs with other ratings.
However, when the event is rare, as in the present example with condemnation rates, the precision of the residuals using the normal model is unstable and may give inaccurate results when applied to the space-time scan statistic [ 20].
In terms of secular changes, results from our multi-level models using lung condemnation data predicted a decline across the study period in all regions.
The fitted model indicated that liver condemnation rates were higher in C rated abattoirs compared to higher rated abattoirs (Table 4).
The fitted model indicated that lung condemnations tended to be lower in higher rated abattoirs compared to C rated abattoirs (Table 3).
On the other hand, condemnation of the model is unjust if it is based on possibly inadequate implementation of the model.
"This is not a condemnation of the model itself but rather its implementation," said Ed Barton, director of digital media at the consultancy Strategy Analytics.
