Figure 9.6
The place field estimates derived from the spatial smoothing model (dotted line),
and the maximum likelihood fits of the inhomogeneous Poisson (IP) (thin solid line),
inhomogeneous gamma (IG) (thin solid line), and inhomogeneous inverse Gaussian
(IIG) models (thick solid line). The units of spikes/sec only apply to the spatial and
IP model fits. For the IG and the IIG models the graphs show the spatial components
of the rate models. The conditional intensity (rate) function for these two models is
obtained from Equation (9.2) in the way Equation (9.33) was used to compute this
quantity in Section 9.3.1.
