true_f: True regression function value

In koohyun-kwon/HTEBandSim: What the Package Does (One Line, Title Case)

Description

True regression function value

Usage

true_f(
  reg.name = c("AK", "AK.bin"),
  reg.spec,
  M,
  x,
  cvar.spec = NULL,
  scale = NULL
)

Arguments

reg.name	class of regression functions to be used; "AK" denotes regression functions in Section 5 of Armstrong and Kolesár (2020); "AK.bin" denotes denotes the case where y = 1(f(x) + u > 0), using regression functions in Section 5 of Armstrong and Kolesár (2020), where u is a normal random variable.
reg.spec	a number denoting the type of regression function among the class of functions chosen in reg.name.
M	bound on the second derivative
x	a vector of x values.
cvar.spec	specification for conditional variance function, one of c("homo", "het.AK").
scale	scale parameter, a positive constant multiplied to the noise.

Value

a vector of true regression function values evaluated at x

Examples

x <- seq(-1, 1, length.out = 50)
true_f("AK", 1, 1, x)
true_f("AK.bin",1, 1, x, "het.AK", 1/2)
