Processing the acute cocaine FMRI response in human brain

Bayesian multivariate technique [7] to process the acute BOLD response to an intravenous dose of cocaine measured in a cocaine-addicted human subject, estimating dependencies between voxels residing within cocaine-sensitive regions. Most FMRI data is currently processed as a set of independent voxelwise tests, resulting in the multiple compar-

statistical estimation and price optimization methods for estimating the optimal solutions and associated con dence intervals. We present a novel and exact reformulation of the problem that leads to the framework which requires as input the estimates of only three distinct aspects of the demand distribution: the mean,

V j(c i) = U j(c i) + e Further, we assume that the functions are linear in feature vectors so we get:1 U j(c i) = f i*B j Finally, we assume that that the individual level utility weights B

Apart from the evidence for the presence of habit persistence and hence different short and long-term elasticities in general, significant differences between countries are also evidenced, in particular between high- and low-income countries and between main geographic areas.

The issue is typically handled with linear life-cycle labor supply equations, which are derived from utility functions that are separable in consumption and leisure.

Then, considering the presence of a single target, we can apply any sparse-signal recovery algo-rithm [20] [22] to determine the paths along which the target response is received. Thus, we transform the target-detection problem into the task of estimating the spectrum of a sparse signal.

In such problems it is of more interest to select the important factors than to understand how the individual derived variables explain the response.
