[R] [R-pkgs] STAR (Spike Train Analysis with R) uploaded on CRAN
Hi all, I've uploaded STAR (Spike Train Analysis with R) on CRAN two days ago. The package is designed to analyze neuronal spike (action potential) trains. It uses S3 classes and methods and makes heavy use of other CRAN packages like gss, R2HTML, mgcv, survival. * Analysis of both spontaneous and stimulus evoked activity is implemented for single neuron spike trains as well as for many neurons recorded simultaneously. * Several bi variate duration distribution can be automatically fitted to "spontaneous" spike trains. Tests for renewal processes are implemented. * A non-parametric, smoothing spline based, approach to the estimation of the conditional intensity of the trains is also available (this feature is under development). * The full collection of Ogata's tests (1988, JASA, 83:9) for point-process models is implemented and the data set used by him (table 1 of the paper) is made available. * A new goodness of fit test for point-process is also proposed based on the fact that the martingale of the process plotted as a function of the integrated conditional intensity starts behaving very quickly as a standard Wiener process (if the model is correct). By the way I have no clean and formal proof of the latter statement so anyone able (and wiling) to give me some help on that is invited to send me an email. * Many data sets are included as well as vignette (covering only part of the present functionalities) and several demos. Any feed-back, comment, critic, is welcome. Christophe -- A Master Carpenter has many tools and is expert with most of them.
