Previous: Introduction
It is assumed that the observed data, , is decomposed into
the addition of the response to the stimulus, , and some
noise process, :

where indexes the voxel and indexes the time (or volume).
Generally, would be a function of the stimulus .
Next we need to turn our attention to the modelling of the
separate components in equation 1, the response to the
stimulus, , and the noise process, .
