Mapping the physiological changes in sleep regulation across infancy and young childhood
Fig 4
Relative contributions of subsets of parameters at different ages in infancy.
a) The minimum cost function value over time for different parameter constraints in Infant 1. b) The total cost value over the first 200 days of Infant 1 (seven day windows from midday 5 to 204). c) The total cost value over the last 200 days of Infant 1 (seven day windows from midday 345 to 544). Subsets of parameters with two fixed parameters have the fixed value from the corresponding single fixed parameter sets (connected by dashed lines in b and c), that is , and b = 1.
