In cmprskWeb: Multistage Competing Risks Analysis for Web data

Description Usage Arguments Value See Also Examples

Data preparation utility function for taking into account the number of visits (within the clickstream) of the starting pages.

1	msprep(linkdata, linkfreq.res, stage.depth = 2, elim = TRUE, sess = TRUE)

`linkdata`	Data frame with session ID, user ID, from, to, dwelltime, covariate
`linkfreq.res`	Result from `linkfreq()` analysis
`stage.depth`	Integer denoting the stage depth
`elim`	It `TRUE` it eliminates PI's larger than stage depth, if `FALSE`, successive PI's go into last stage
`sess`	If `TRUE`, analysis is performed at session level, otherwise at user level

Returns a data frame suited for multistage competing risks modeling.
