The board will have considered any reports from psychologists and probation officers and will have looked at any statistical risk assessments that have been completed.
After 15 years the reduction in risk achieved statistical significance, and by 20 years the risk was similar to women who had never smoked.

It was more common for identical twins to both have Alzheimer's compared to non-identical, and a statistical analysis of risk rates in the groups gave the researchers their estimate of how significant genetic factors are.
He pooled data from two much larger ongoing studies of Vytorin and said they showed that the cancer risk was a statistical fluke.
The engineering and statistical tools exist, from probabilistic risk assessment (PRA) to meta-data analytics.

This is a fancy way of saying that statistical significance is not the only way to measure risk.
That translates into a 16% reduction in risk that is highly unlikely, according to statistical tests, to be due to chance.
First, they want to build statistical models mapping the severity and frequency of past operational risk losses and use this to judge the amount of the bank's capital at risk from operational failures in the future.
The limitations of statistical methods to fully model, and therefore properly describe, risk.
It did seem to extend survival in a clinical trial, but there was an 18% risk that the results were simply due to chance--a statistical measure that usually causes scientists to believe results are not necessarily true.
Some experts have cast doubt on whether the statistical analysis used to interpret the data in the study gives an accurate assessment of true risk.
The subject has been so roundly ignored that the 900-page bible of psychiatry, the Diagnostic and Statistical Manual of Mental Disorders IV, offers no advice for doctors on how to assess suicide risk.
The authors did this comparison because while randomised trials of aspirin could clearly establish the risk of colorectal cancer, several other solid cancers, and of metastasis, these trials lacked the statistical power to establish effects on less common cancers and on cancers in women.
