qpgeeControl: Control Parameters for qpgee

In geeVerse: A Comprehensive Analysis of High Dimensional Longitudinal Data

Control Parameters for qpgee

Description

Provides control parameters for the Quantile Penalized Generalized Estimating Equations (QPGEE) fitting procedure. Similar in spirit to 'geese.control()' in the geepack package.

Usage

qpgeeControl(
  epsilon = 1e-04,
  decay = 1,
  maxit = 100,
  trace = FALSE,
  standardize = FALSE,
  shrinkCutoff = 1e-04
)

Arguments

epsilon	Convergence tolerance for the parameter estimates. Iteration stops when the maximum change in coefficients is below this value.
decay	Decay rate of learning step.
maxit	Maximum number of iterations.
trace	Logical indicating if output should be produced for each iteration. (You can decide how much information to show inside the C++/R loop.)
standardize	Logical indicating whether to scale X.
shrinkCutoff	Threshold below which coefficients are shrunk to zero (removal of “small” coefficients).

Value

A list with the components epsilon, maxit, trace, and shrinkCutoff.

Examples

ctrl <- qpgeeControl(epsilon = 1e-5, maxit = 200, trace = TRUE)
