Abstract: itdidbounds computes numerical timing-uncertainty envelopes for difference-in-differences/event-time contrasts when treatment adoption timing is known only to lie within unit-specific intervals. The command enumerates feasible adoption dates and reports the minimum and maximum contrast estimates across those timing assignments. These envelopes characterize sensitivity to interval-known treatment timing; they are not automatically causal treatment-effect bounds or confidence intervals.
