Table 3.

Estimates of the Trait and Initial State Parameters for the 3 Individual Subjects, as Converged on After 88 H of Total Sleep Deprivation in Computer Simulations Starting 24 H After Awakening.

Individual Trait Parameters
State Parameters
ν η λ ξ ϕ
A 0.47 0.76 0.0 −44.5 0.0
B −2.05 −0.32 −3.9 −31.0 3.2
C 1.38 0.11 3.4 * −3.0

ξ could not be estimated from subject C's data after 24 h of wakefulness, as this parameter no longer had a noticeable effect on the subject's performance predictions.
