Gaussian HRF (hemodynamic response function)

The `hrf_gaussian` function computes the Gaussian density-based HRF (hemodynamic response function) at given time points `t`.

Usage

hrf_gaussian(t, mean = 6, sd = 2)

Arguments

t

A vector of time points.

mean

A numeric value representing the mean of the Gaussian probability density function. Default value is 6.

sd

A numeric value representing the standard deviation of the Gaussian probability density function. Default value is 2.

Value

A numeric vector representing the Gaussian HRF at the given time points `t`.
