A Comparison between Alternative Volatility Estimations Application on Blood Oxygen Concentration of Preterm Infants

The medical measurements for preterm babies manifest instabilities because of their under-developed biological systems. These physiological instabilities raise the question of whether a preterm baby is simply premature or is likely to develop long-term health complications. Because instabilities are of concern, useful information about the health state of preterm infants can be expected to be contained in the variations of the medical measurements. However, instantaneous variations are not observed directly along with the physiological measurements, and so suitable models must be employed to estimate them.
