StationaryInverseGaussianProcess
(rate: Quantity, cv: float, t_start: Quantity = array(0.) * s, t_stop: Quantity = array(1.) * s, equilibrium: bool = True)[source]¶ Generates spike trains whose spikes are realizations of a stationary Gamma process with the given rate and cv starting at time t_start and stopping at time t_stop.
Parameters: - ratepq.Quantity
The constant firing rate.
- cvfloat
The expected coefficient of variation.
- t_startpq.Quantity, optional
The start of the spike train. Default: 0.*pq.s
- t_stoppq.Quantity, optional
The end of the spike train. Default: 1.*pq.s
- equilibriumbool, optional
Generate an equilibrium or an ordinary renewal process. Default: True
Raises: - ValueError
If one of rate, t_start and t_stop is not of type pq.Quantity.
Examples
>>> import quantities as pq >>> spiketrain = StationaryInverseGaussianProcess( ... rate=50*pq.Hz, cv=2.0, t_start=0*pq.ms, ... t_stop=1000*pq.ms).generate_spiketrain() >>> spiketrain_array = StationaryInverseGaussianProcess( ... rate=20*pq.Hz, cv=5.0, t_start=5000*pq.ms, ... t_stop=10000*pq.ms).generate_spiketrain(as_array=True)
Methods
__init__
(rate, cv[, t_start, t_stop, ...])generate_n_spiketrains
(n_spiketrains[, as_array])Generates a list of spike trains. generate_spiketrain
([as_array])Generates a single spike train. Attributes
expected_cv
The expected coefficient of variation given the ISI distribution. t_start
t_start quantity; there are no spike times below this value. t_stop
t_stop quantity; there are no spike times above this value. -
property
expected_cv

generate_n_spiketrains
(n_spiketrains: int, as_array: bool = False) Union[List[SpikeTrain], List[ndarray]] ¶ Generates a list of spike trains.
Parameters: - n_spiketrainsint
The number of spike trains to generate.
- as_arraybool, optional
If True, a NumPy array of sorted spikes is returned, rather than a neo.SpikeTrain object. Default: False
Returns: - list_of_spiketrainlist of neo.SpikeTrain or list of np.ndarray
A list generated spike trains in the specified format.
-
generate_spiketrain
(as_array: bool = False) Union[SpikeTrain, ndarray] ¶ Generates a single spike train.
Parameters: - as_arraybool, optional
If True, a NumPy array of sorted spikes is returned, rather than a neo.SpikeTrain object. Default: False
Returns: - spiketrainneo.SpikeTrain or np.ndarray
The generated spike train in the specified format.
