function to generate a initial EW Design for generalized linear models

Description

function to generate a initial EW Design for generalized linear models

Usage

EW_design_initial_GLM(
  k.continuous,
  factor.level,
  Integral_based,
  b_matrix,
  joint_Func_b,
  Lowerbounds,
  Upperbounds,
  xlist_fix = NULL,
  lvec,
  uvec,
  h.func,
  link = "continuation",
  delta0 = 1e-06,
  epsilon = 1e-12,
  maxit = 1000
)

Arguments

k.continuous	number of continuous variables
factor.level	list of distinct factor levels, “(min, max)” for continuous factors that always come first, finite sets for discrete factors.
Integral_based	TRUE or FALSE, whether or not integral-based EW D-optimality is used, FALSE indicates sample-based EW D-optimality is used.
b_matrix	matrix of bootstrapped or simulated parameter values.
joint_Func_b	prior distribution function of model parameters
Lowerbounds	vector of lower ends of ranges of prior distribution for model parameters.
Upperbounds	vector of upper ends of ranges of prior distribution for model parameters.
xlist_fix	list of discrete factor experimental settings under consideration, default NULL indicating a list of all possible discrete factor experimental settings will be used.
lvec	lower limit of continuous variables
uvec	upper limit of continuous variables
h.func	function, is used to transfer the design point to model matrix (e.g. add interaction term, add intercept)
link	link function, default "continuation", other options "baseline", "adjacent" and "cumulative"
delta0	tuning parameter, the distance threshold, || x_i(0) - x_j(0) || >= delta0
epsilon	determining f.det > 0 numerically, f.det <= epsilon will be considered as f.det <= 0
maxit	maximum number of iterations

Value

X matrix of initial design point

p0 initial random approximate allocation

f.det the determinant of the expected Fisher information matrix for the initial design
