In zhenkewu/baker: "Nested Partially Latent Class Models"

Make Etiology design matrix for dates with R format.

Description

s_date_Eti creates design matrices for etiology regressions;

Usage

s_date_Eti(Rdate, Y, basis = "ps", dof = ifelse(basis == "ncs", 5, 10), ...)

Arguments

Rdate	a vector of dates of R format
Y	Binary case/control status; 1 for case; 0 for controls
basis	ncs for natural cubic splines; ps for penalized-splines based on B-spline basis functions (NB: baker does not recommend setting ncs using this function; use splines::ns)
dof	Degree-of-freedom for the bases. For ncs basis, dof is the number of columns; For ps basis, the number of columns is dof if intercept=TRUE; dof-1 if FALSE.
...	Other arguments as in splines::bs()

Value

• Z_Eti design matrix for etiology regression on dates.
