cpp_compute_occ_exp
cpp_compute_occ_exp.Rdcompute occurrences and exposures from lifelines, age groups, and time intervals
Arguments
- lambda
a matrix of lifelines whose rows are units of observation (individuals), and whose columns are (in order): start time, end time, event time
- alpha
a matrix whose rows are age groups and whose columns are (in order): start time, end time (both starting from 0)
- alpha_offset
a vector with the birthdate of each unit of observation or, more generally, the offset to use for the age groups in alpha
- tau
a matrix of time periods whose rows are units of observation (individuals), and whose columns are (in order): start time, end time
Value
a list containing two matrices, 'occ' and 'exp. each matrix has one row for each unit of observation (individua) whose columns are (for exp, in order): age group 1 exposure, ..., last age group exposure; and (for occ, in order) age group 1 number of events, ..., last age group number of events
