buildrisksets function

Calculation of risksets needed for partial likelihood formulation of multistate models.

This function calculates the risksets needed to calculate the partial likelihood of a multistate model, and/or it's derivatives.

buildrisksets(entry, exit, trans, event, trace)

Arguments

• entry: vector with entry times.
• exit: vector with exit times.
• trans: vector with transition types.
• event: vector with noncensoring event indicators.
• trace: logical triggering printout of status information during the fitting process.

Details

This function calculates risksets.

Returns

A list of length 2 with elements Ci and Ri, each vectors of length n.
