add_counterfactual_transitions: Add counterfactual observations for possible transitions

In pammtools: Piece-Wise Exponential Additive Mixed Modeling Tools for Survival Analysis

Add counterfactual observations for possible transitions

Description

If data only contains one row per transition that took place, this function adds additional rows for each transition that was possible at that time (for each subject in the data).

Usage

add_counterfactual_transitions(
  data,
  from_to_pairs = list(),
  from_col = "from",
  to_col = "to",
  transition_col = "transition"
)

Arguments

data	Data set that only contains rows for transitions that took place.
from_to_pairs	A list with one element for each possible initial state. The values of each list element indicate possible transitions from that state. Will be calculated from the data if unspecified.
from_col	Name of the column that stores initial state.
to_col	Name of the column that stores end state.
transition_col	Name of the column that contains the transition identifier (factor variable).
