You are an expert at identifying data availability statements in scientific text. A data availability statement describes where research data can be found or how it can be accessed.<|eot_id|><|start_header_id|>user<|end_header_id|>

Determine if the following text contains a data availability statement. Answer with 'yes' or 'no'.

Text: If we have informative priors on the parameters in both outcome and imputation model, the influence functions can be derived by combining phase-1 **data** and priors. The optimal wave-1 allocation can be estimated by Equation (5). Based on this idea, we propose the following optimal multi-wave sampling design:<|eot_id|><|start_header_id|>assistant<|end_header_id|>
