soControl: Control values for order-constrained fit

Description Usage Arguments Value Author(s) See Also Examples

View source: R/Reprod.R

Description

The values supplied in the function call replace the defaults and a list with all possible arguments is returned. The returned list is used as the control argument to the mc.est, SO.LRT, and SO.trend.test functions.

Usage

soControl(method = c("ISDM", "EM"), eps = 0.005, max.iter = 5000,
  max.directions = 0, start = ifelse(method == "ISDM", "H0",
  "uniform"), verbose = FALSE)

Arguments

method

a string specifying the maximization method

eps

a numeric value giving the maximum absolute error in the log-likelihood

max.iter

an interger specifying the maximal number of iterations

max.directions

an integer giving the maximal number of directions considered at one step of the ISDM method. If zero or negative, it is set to the number of non-empty cells. A value of 1 corresponds to the VDM algorithm.

start

a string specifying the starting setup of the mixing distribution; "H0" puts weight only on constant vectors (corresponding to the null hypothesis of no change), "uniform" puts equal weight on all elements. Only a "uniform" start can be used for the "EM" algorithm.

verbose

a logical value; if TRUE details of the optimization are shown.

Value

a list with components for each of the possible arguments.
