s_date_FPR function

Make false positive rate (FPR) design matrix for dates with R format.

s_date_FPR creates design matrices for FPR regressions;

s_date_FPR(Rdate, Y, basis = "ps", dof = 10, ...)

Arguments

• Rdate: a vector of dates of R format

• Y: Binary case/control status; 1 for case; 0 for controls

• basis: "ps" for penalized-splines based on B-spline basis functions

• dof: Degree-of-freedom for the bases.For "ps" basis, the number of columns is dof

  if intercept=TRUE; dof-1 if FALSE.

• ...: Other arguments as in splines::bs()

Returns

Design matrix for FPR regression, with cases' rows on top of controls'.

Examples

data(data_nplcm_reg_nest)
s_date_FPR(data_nplcm_reg_nest$X$DATE,data_nplcm_reg_nest$Y,basis='ps',dof=7)
