Defaults for the gsm call

Description

Set useful default and allow changes for the gsm call. This is meant to make the gsm call simpler.

Usage

gsm.control(parscale = 1, maxit = 300, optimiser = c("BFGS", "NelderMead"), trace = 0,
            nodes = 9, adaptive = TRUE, kappa.init = 1, maxkappa = 1000,
            suppressWarnings.coxph.frailty = TRUE, robust_initial = FALSE, bhazinit = 0.1,
            eps.init = 1e-5, use.gr = TRUE, penalty = c("logH", "h"), outer_optim = 1,
            reltol.search = 1e-10, reltol.final = 1e-10, reltol.outer = 1e-05,
            criterion = c("GCV", "BIC"), old.init=FALSE)

Arguments

`parscale`	numeric vector or scalar for the scaling of the parameter values; default 1
