Whereas in calculate_stipw() the names are hardcoded for the Berkeley Study simulation; We aim here to generalize the stipw for the HIV application. Thus the name calculate_stipw_generic().
1 | calculate_stipw_generic(data_in = NULL, na.action = "omit")
|
data_in |
a data.table (see the data.table package, Tutorial, and FAQs) that is in long format of at least the id, time, and outcome and some covariates for the probability weights. |
na.action |
"keep" means the dataset returned will be same number of rows as data_in and "omit" discards all data past censoring observation |
a data.table similar to data_in with stipw in columns; and potentially fewer rows or NA-filled rows for induced censoring.
