These include the coefficients for the kernels, β, and the Laguerre pole, α. The mean correlation coefficient (CC) obtained from the cross‐validation approach (see text) is also shown for each model, including the stimulus time course (boxcar). The standard errors of mean (SEMs) for the correlation coefficient are shown in parenthesis.
