Trying to simplify the concept, it may be stated that the group-level residual, for each centre, represents the distance between its estimated mortality and the overall estimated mortality.
The HL statistics is a single summary measure of the calibration and is based on comparing the observed and estimated mortality for patients grouped by estimated mortality.
RAFFI KHATCHADOURIAN: The estimated mortality for birds in the Exxon Valdez spill is a quarter of a million.
The estimated mortality rates were directly related to the time that had elapsed since each drug was approved.
Britain has 1,316 deaths a year, with an estimated mortality rate of 30.5 per million adults.
That might be a greater toll than the Rwandan genocide and is approaching the scale of the estimated mortality from the Democratic Republic of Congo's overlapping, longer-running civil wars.
As a benchmark, the deadliest influenza pandemic in the past century, the Spanish influenza of 1918 to 1919, had an estimated mortality rate of around 2.5percentt but killed tens of millions of people because it spread so widely.

Long-term immunosuppressants and anti-inflammatories carry significant morbidity, estimated mortality is 6.8% while the most frequent predictors are: active SLE, thromboses, and infections, respectively [1].
Mean Saps 3 score was 44.1 (SD 7.8) while mean Grace index was 152.8 (DE 37.6) Estimated mortality by Saps 3 and Grace were 12.0 % and 5.1%% respectively.
The analysis of the severity index points to an estimated mortality higher than the observed, exposing a high quality of care provided.
