classo.control: internal classo parameters

Description

View and/or change the factory default parameters in classo

Usage

classo.control(
  fdev = 1e-05,
  devmax = 0.999,
  eps = 1e-06,
  big = 9.9e+35,
  mnlam = 5,
  pmin = 1e-09,
  exmx = 250,
  prec = 1e-10,
  mxit = 100,
  itrace = 0,
  epsnr = 1e-06,
  mxitnr = 25,
  factory = TRUE
)

Value

A list with named elements as in the argument list

Arguments

fdev: minimum fractional change in deviance for stopping path; factory default = 1.0e-5
devmax: maximum fraction of explained deviance for stopping path; factory default = 0.999
eps: minimum value of lambda.min.ratio (see classo); factory default= 1.0e-6
big: large floating point number; factory default = 9.9e35. Inf in definition of upper.limit is set to big
mnlam: minimum number of path points (lambda values) allowed; factory default = 5
pmin: minimum probability for any class. factory default = 1.0e-9. Note that this implies a pmax of 1-pmin.
exmx: maximum allowed exponent. factory default = 250.0
prec: convergence threshold for multi response bounds adjustment solution. factory default = 1.0e-10
mxit: maximum iterations for multiresponse bounds adjustment solution. factory default = 100
itrace: If 1 then progress bar is displayed when running classo and cv.classo. factory default = 0
epsnr: convergence threshold for classo.fit. factory default = 1.0e-6
mxitnr: maximum iterations for the IRLS loop in classo.fit. factory default = 25
factory: If TRUE, reset all the parameters to the factory default; default is FALSE

Details

If called with no arguments, classo.control() returns a list with the current settings of these parameters. Any arguments included in the call sets those parameters to the new values, and then silently returns. The values set are persistent for the duration of the R session.

Examples

Run this code


classo.control(fdev = 0)  #continue along path even though not much changes
classo.control()  # view current settings
classo.control(factory = TRUE)  # reset all the parameters to their default
