     In addition, compare the distributions with the Poisson
     distribution expected for a Poisson spike train:
-    \[ P(k) = \frac{(\lambda W)^ke^{\lambda W}}{k!} \; , \] where
+    \[ P(k) = \frac{(\lambda W)^ke^{-\lambda W}}{k!} \; , \] where
     $\lambda$ is the rate of the spike train that you should estimate
     from the data.
