Treatment of Outliers
Providers highlighted as outliers from deploying the process described above were discussed through a multidisciplinary group of LA officers to ensure that they were being treated consistently, transparently and fairly. Hounslow endeavoured to retain as much data as possible due to the relatively small sample size.
Future modelling and exercises would need to consider additional data from relevant other local authorities, benchmarking or alternative open book approach exercises to further enhance outputs robustness and validity. DHSC guidance on appropriate benchmarking was not available for this exercise.
