RankInit-class function

RankInit Class

A S4 class to store initialization information of model fitting

The RankInit class is used to give initial values of model fitting procedures. class

Slots

• param.init: a list containing initial values of the positive parametrization of weights.
• modal_ranking.init: a list containing starting points for the modal ranking search.
• clu: an integer containing the number of clusters used in the model.
• p.init: a numeric vector containing the initial values for cluster probabilities.

Examples

c1init = new("RankInit",param.init=list(rep(1,4)),
     modal_ranking.init=list(c(2,3,4,1,5)),clu=1L)
c2init = new("RankInit",param.init=list(rep(0.1,4),rep(0.1,4)),
     modal_ranking.init = list(c(2,3,4,1,5),c(2,5,1,4,3)),clu=2L,p.init=c(0.5,0.5))
