What you get with this Offer
I will write SAS programs to clean and prepare up to 5 datasets — covering missing value imputation or flagging, duplicate record identification and resolution, character and numeric format standardisation, outlier detection and capping, derived variable creation, and output of clean, analysis-ready SAS datasets with full variable labels and formats applied. Clean, consistently structured SAS datasets are the foundation of reliable analysis and regulatory reporting; poorly prepared data produces results that appear plausible but contain systematic errors discovered only when audited.
The programs use efficient DATA step techniques (WHERE clause filtering, RETAIN statement, array processing for batch variable transformations) and PROC SQL for set operations and complex derivations. A data quality report generated via PROC MEANS, PROC FREQ, and PROC UNIVARIATE is included, documenting the before/after state of each dataset.
Suitable for clinical research organisations, financial institutions, government agencies, and any organisation using SAS for structured data preparation before statistical analysis or reporting.
