Coefficient functions from the function-on-scalar regression with the PD profile as an outcome. Each dark line represents the coefficient function, and the shaded area represents a bootstrapped, point-wise 95% confidence interval. Along the x-axis of each plot is the time in days from lesion incidence. Along the y-axis is the value of the coefficient function at each time point. Only distance from the boundary and age were found to be different from 0 at any point along the profile.
