Statistics of spike trains¶
Statistical measures of spike trains (e.g., Fano factor) and functions to estimate firing rates.
Rate estimation¶
|
Return the firing rate of the spike train. |
|
Estimates instantaneous firing rate by kernel convolution. |
|
Time Histogram of a list of neo.SpikeTrain objects. |
|
Calculates optimal fixed kernel bandwidth (Shimazaki and Shinomoto, 2010), given as the standard deviation sigma. |
Spike interval statistics¶
|
Return an array containing the inter-spike intervals of the spike train. |
|
Compute the coefficient of variation. |
|
Calculate the measure of Cv2 for a sequence of time intervals between events (Holt et al., 1996). |
|
Calculate the measure of local variation Lv for a sequence of time intervals between events (Shinomoto et al., 2003). |
|
Calculate the measure of revised local variation LvR for a sequence of time intervals between events (Shinomoto et al., 2009). |
Statistics across spike trains¶
|
Evaluates the empirical Fano factor F of the spike counts of a list of neo.SpikeTrain objects. |
|
Complexity Distribution of a list of neo.SpikeTrain objects (Grün et al., 2007). |
|
