Abstract:
|
Alcohol biosensor devices have the prospect to positively impact medicine and law enforcement by giving a noninvasive method to acquire continuous alcohol readings. We propose to develop a nonparametric estimation algorithm that estimates the joint distribution of the parameters of the model which are assumed to be random due to natural irregularity in an individual’s body conditions and the variability of population data. This is superior to parametric estimation methods since it can capture unusual fluctuations of a subject's condition as well as environmental factors. This will help to ascertain a precise relation between blood alcohol concentration and transdermal alcohol concentration. We are using a stochastic differential equation model to estimate the diffusion of alcohol through transdermal layers using a nonparametric maximum likelihood approach while taking into account noise in the data.
