We develop two benchmark approaches, both of which solve chance-constrained programs with fixed risk values in a bisection algorithm or by enumeration.
As a crude approach, we again assumed a fixed risk allele frequency of 0.5 so that log(OR) and the standard error (SE) can be estimated from z-values.
Tables 3, 4, 5 present estimates of fixed risk factors resulting from the models with the best fit.
Subsequently, 898 patients were assessed for a limited number of fixed risk factors with the addition of hypotension and sepsis.
A number of fixed risk factors which have been shown to affect psychological distress in later life are age, gender and educational status [ 8].
The model further assumes homogeneous infectivity during the duration D (Dm in males, Df in females) of HIV infection, and a fixed risk of transmission per partnership, viz.

Anti-bullying regulations, zero-tolerance policies, metal detectors and police officers in schools all send the same message: young people are problems to be fixed, risks to be managed.
Of the fixed risks, age remained significant, uniquely accounting for 0.9% of the variance.
Similar patterns were also observed by Van Calster and others when they varied the cutpoint and assumed a fixed mean risk; as the cutpoint moved away from mean risk the reclassification measures provided a more optimistic view of the new predictor compared to that provided by the difference in net benefit [ 16].
The S-RAMM-C scale performed well but the S-RAMM-B (background or fixed historical risk factors for suicide), S-RAMM-F ('future' risk factors for suicide), START-S and START-V were notable for their lack of predictive capability for self harm in this study.
