Nonparametric estimation of characteristics of the interspike interval distribution
BMC Neuroscience volume 16, Article number: P131 (2015)
We address the problem of non-parametric estimation of the probability density function as a description of the probability distribution of noncorrelated interspike intervals (ISI) in records of neuronal activity. We also continue our previous effort [1, 2] to propose alternative estimators of the variability measures. Kernel density estimators are probably the most frequently used non-parametric estimators of the probability distribution. However, there are also other non-parametric approaches. We focus on non-parametric methods based on a principle of extrema of the Fisher information. Specifically, we focus on the maximum penalized likelihood estimation of the probability density function proposed by Good and Gaskins , which can be understood as a kernel estimator with a particular kernel function . Other non-parametric approach we would like to address is the spline interpolation proposed by Huber  which can uniquely estimate the ISI distribution.
