sssSetup-class: Class '"sssSetup"'

In Sage-Bionetworks/sss: Shotgun Stochastic Search (SSS) from Hans, Dobra and West

Objects from the Class

Objects of class sssSetup are completely specified by calling sss - the defaults of each slot are presented below. Individual slots can be overriden by specifying in ... of sss.

Slots

nobservations:

Object of class "numeric" - AUTOMATICALLY SET BY sss

nvariables:

Object of class "numeric" - AUTOMATICALLY SET BY sss

datafile:

Object of class "character" - AUTOMATICALLY SET BY sss

responsefile:

Object of class "character" - AUTOMATICALLY SET BY sss

weightsfile:

Object of class "character" - AUTOMATICALLY SET BY sss

censorfile:

Object of class "character" - AUTOMATICALLY SET BY sss

modtype:

Object of class "numeric" - AUTOMATICALLY SET BY sss

outfile:

Object of class "character" - AUTOMATICALLY SET BY sss

iterout:

Object of class "character" - AUTOMATICALLY SET BY sss

summaryfile:

Object of class "character" - AUTOMATICALLY SET BY sss

priormeanp:

Object of class "numeric" - default is 5 - prior mean of number of included variables (this is the key sparsity control parameter) - priormeanp=v means that each variable is "in the model" with prior probability v/(number of predictors)

pstart:

Object of class "numeric" - default is 2 - initial model size (number of predictors for model to start sss)

pmax:

Object of class "numeric" - default is 15 - maximum model size (maximum number of predictors in any model)

onevar:

Object of class "numeric" - default is 1 - indicator to include all 1-variables models in search

iters:

Object of class "numeric" - default is 100 - total number of sss iterations

nbest:

Object of class "numeric" - default is 10 - number of best models to be saved/recorded

inneranneal1:

Object of class "numeric" - default is 0.6 - annealing parameter for variable replacement (DEFAULTS SHOULD BE USED)

inneranneal2:

Object of class "numeric" - default is 0.8 - annealing parameter for variable detection (DEFAULTS SHOULD BE USED)

inneranneal3:

Object of class "numeric" - default is 1 - annealing parameter for variable addition (DEFAULTS SHOULD BE USED)

outeranneal:

Object of class "numeric" - default is 0.4 - annealing parameter for second level model selection (DEFAULTS SHOULD BE USED)
