Summarize CATE Estimates and Dynamic Treatment Rule Across Segments

Produce a summary of the segments and the segment-specific treatment rule assignment based on estimates of the conditional average treatment effect (CATE) within each segment. When the dynamic treatment rule has not yet been assigned via assign_rule, just segment specific summaries of the CATE estimates and their standard error are returned.

summarize_segments(data_with_rule)

Arguments

data_with_rule

data_with_rule	A `data.table` containing the input data, augmented with cross-validated nuisance parameter estimates, an estimate of the CATE, and a treatment rule assigned based on the estimated CATE via `assign_rule`. This input object should be created by successive calls to `set_est_data`, `est_cate`, and `assign_rule` in a sequence, or through a wrapper function that composes these function calls automatically. When `assign_rule` has not been called, summary of the rule assignment and relevant evaluation of the CATE is skipped and only segment-specific CATE summaries are output.

Value

A data.table containing the discovered segments, the estimated CATE within each segment (with inference for the CATE), the segment-specific treatment rule assignment, and auxiliary info for assessing the quality of the segmentation.
