modify_transMat function

Upgrade the transMat object for the multi-state/relsurv setting.

A function that upgrades the transMat object so that the population and excess-related transitions are included in the transition matrix.

modify_transMat(trans, split.transitions)

Arguments

• trans: The original transition matrix (usually generated using function transMat from mstate). Also often present in the msfit object.
• split.transitions: The transitions that should be split.

Returns

An upgraded transition matrix that contains the population and excess transitions.

Examples

# transition matrix for illness-death model
trans <- transMat(list(c(2,3),c(4), c(), c()), 
      names = c("Alive", "Relapse","Non-relapse mortality", "Death after relapse"))
split.transitions <- c(2,3)
modify_transMat(trans, split.transitions)
