Our results support that when the latent variable model of the regressors hold, substitute adjustment is a viable method for adjusted regression.

Based on our theoretical results, we propose the Debiased Outcome-adapted Propensity Estimator (DOPE) for efficient estimation of the ATE, and we provide asymptotic results for the DOPE under general conditions.

It describes whether the evolution of one process is directly influenced by another process given the histories of additional processes, and it is important for the description and learning of causal relations among processes.

Existing tests require strong model assumptions, e. g. that the true data generating model is a Hawkes process with no latent confounders.

Computation and storage of its tensor product design matrix can be impossible due to time and memory constraints, and previously considered design matrix free algorithms do not scale well with the dimension of the parameter vector.
