Fits a duration model to isis from a spike train. Confidence intervals are also drawn.
1  isiHistFit(spikeTrain, model, nbins = 10, CI = 0.95, ...)

spikeTrain 
a 
model 
a character vector whose elements are selected among:

nbins 
the number of bins to use. 
CI 
the confidence coefficient. 
... 
additional arguments passed to 
Assuming that the train is reasonably well described by a renewal process,
a model
distribution is fitted to the interspike intervals
(isis) obtained from spikeTrain
. The fitted distribution is
then used to set the histogram breaks such that a uniform bin
count would be expected if the fitted distribution was the true
one. Confidence segments are also obtained from the binomial
distribution. The histogram is build and the fitted density together
with confidence intervals are drawn.
Nothing returned, isiHistFit
is used for its side effect, a
plot is generated on the current graphic device.
