Web3. A reluctant argument for it, on occasion: It can simplify clinical interpretation and the presentation of results - eg. blood pressure is often a quadratic predictor and a clinician can support the use of cutoffs for low, normal and high BP and may be interested in comparing these broad groups. – user20650. WebThe former is usually obtained by binning spike trains, whereas the stan-dard method for the latter is smoothing with a Gaussian kernel. Selection of a bin width or a kernel size is often done in an relatively arbitrary fashion, even though there have been recent attempts to remedy this situation [1, 2]. We develop an
