Control parameters for mixqr()

Control parameters for mixqr()

Usage

mixqr_control(
  tol = 1e-06,
  maxit = 500L,
  reltol = TRUE,
  bandwidth = NULL,
  kde_grid = 512L,
  label_order = "slope",
  distinct_tol = 0.001,
  trace = FALSE,
  seed = NULL
)

Arguments

tol

Convergence tolerance on the summed absolute parameter change (Wu & Yao 2016, p. 164). Default 1e-6.

maxit

Maximum EM iterations. Default 500.

reltol

Logical; if TRUE use the relative criterion sum|dtheta| / (sum|theta| + eps) < tol (recommended because pi and beta differ in scale). Default TRUE.

bandwidth

Optional numeric KDE bandwidth override (kdEM engine). If NULL, Silverman's rule 1.06 * sd * n^(-1/5) is used per component.

kde_grid

Number of grid points for stored KDE evaluation / plotting. Default 512.

label_order

Label-switching constraint: "slope" (ascending first slope coordinate, default – aligned with the distinct-slope identifiability of Wu & Yao Thm 2.1), "intercept", or "slope:k" for the k-th slope.

distinct_tol

RELATIVE threshold below which component slope vectors are flagged as near-coincident (near-violation of Wu & Yao Thm 2.1), measured as ||b_a - b_b|| / (||b_a|| + ||b_b||). Default 1e-3.

trace

Logical; print iteration progress. Default FALSE.

seed

Optional integer RNG seed for reproducible multi-start.

Value

A list of class "mixqr_control".
