Usage

OverviewEpisodes(Bdata,seq.ind)

Arguments

Bdata

input data: Biograph object

seq.ind

individual state sequences. If seq.ind is missing, the function calls Sequences.ind to obtain the individual state sequences.

Value

n

Sample size

ne

Total number of episodes

nt

Total number of transitions

types

Number of episodes by type [open. closed]

Open intervals start before onset of observation (left truncated) or continue after observation ends (right censored). Closed intervals start and end during the observation period.
