Text: We need to prepare for an experimental dataset D E and an observational dataset D O . For the experimental dataset, we directly use **data** from San Diego, which includes n (1) E = 6978 people in the treatment group and n (0) E = 1154 people in the control group. For the observational dataset, we consider inject synthetic confounding into the Riverside **data** (which originally include N 1 = 4405 people in the treatment group and N 0 = 1040 people in the control group).<|eot_id|><|start_header_id|>assistant<|end_header_id|>
