comparecc {gRc} | R Documentation |
A general function for pairwise comparisons of colour classes in an RCOX model, i.e. for testing whether the corresponding parameters are significantly different
comparecc(object, cc1 = NULL, cc2 = NULL, type = "ecc", stat = "wald", details = 1)
object |
An RCOX model, an object of class 'rcox' |
cc1, cc2 |
Lists of colour classes of type 'type', see 'details' for an explanation of the defaults. |
type |
Either "ecc" for edge colour classes or "vcc" for vertex colour classes |
stat |
Base the comparison on either "wald" for a Wald statistic or "dev" for a deviance statistic |
details |
Control the amount of output created. |
All colour classes specified in cc1
are
compared with all those
given in cc2
(duplicate entries are not compared). If
cc2=NULL
(the default) then all colour classes specified in
cc1
are compared with all colour classes in the model except
those specified in cc1
. If cc1=NULL
(the default) and
cc2=NULL
then all pairwise comparisons are made.
