stremr output

[marycombs]

Can you help me understand the output of stremr? In the optimal dynamic treatment rule example, in the output table IPW_estimates, there are the variables: sum_Y_IPAW, sum_all_IPAW, ht, St.IPTW, ht.KM. Can you help me understand how to interpret each of these variables?

Please let me know which specific functions you are running.

As far as the variables above are involved, it appears that these are the output of survNPMSM

Here are the relevant variables defined in the source code:

https://github.com/osofr/stremr/blob/e6cd51cea0531883cd195ed61f6f72b93b45528b/R/main_estimation.R#L842
Sum of the weighted outcomes (Y multiplied by propensity score cumulative weight), by time-point

https://github.com/osofr/stremr/blob/e6cd51cea0531883cd195ed61f6f72b93b45528b/R/main_estimation.R#L846
Sum of the cumulative propensity scores, by time-point.

The rest of the definitions of the variables can be found similarly, by browsing the function. Briefly, ht is the IPW-hazard, by time-point, St.IPTW is the IPW estimator obtained from that hazard, ht.KM is the Kaplan-Meier hazard.
