Control Parameters for ic_sp

Description

Control Parameters for ic_sp

Usage

makeCtrls_icsp(useGA = T, maxIter = 10000, baseUpdates = 5, regStart = NULL)

Arguments

`useGA`	Should constrained gradient ascent step be used?
`maxIter`	Maximum iterations
`baseUpdates`	number of baseline updates (ICM + GA) per iteration
`regStart`	Initial values for regression parameters @description Creates the control options for the `ic_sp` function. Defaults not intended to be changed for use in standard analyses.

Details

The constrained gradient step, actived by useGA = T, is a step that was added to improve the convergence in a special case. The option to turn it off is only in place to help demonstrate it's utility.

regStart also for seeding of initial value of regression parameters. Intended for use in “warm start" for bootstrap samples and providing fixed regression parameters when calculating fit in qq-plots.
