EW_design_initial_GLM: 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
)

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

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
