# Bang Tsiatis Partitioned Estimator

For example if I have 100 patients in part 1 and 80 in part 2.

To calculate the BT estimator, should I be calculating an average cost among uncensored patients (80?) or among the 100 for partition 2? I’m a little confused by the texts that I’m reading.

Thanks for your help!
