Calculate Bayesian Smoothing Spline (BSS) for Integers

Calculate Bayesian Smoothing Spline (BSS) for Integers

B1(x)

B2(x)

B4(x)

bss(x, n_basis, first_two = TRUE)

Arguments

x

for bss, an integer vector to calculate the basis expansion for. For B1, B2, B4: a numeric vector between 0 and 1.

n_basis

Number of basis terms to use

first_two

Should the first two BSS terms (linear and quadratic) be included?

Details

Currently this does no linear interpolation and so relies on integer (discrete) inputs.
