Advanced SampleCalc Techniques for Power Users

1. Automation & macros

• Use VBA macros to automate repetitive analyses (import → clean → calc → export). Encapsulate sampling logic and confidence-interval choices in reusable functions.
• Trigger macros via custom ribbon buttons for one-click workflows.

2. Complex sampling designs

• Two-stage & cluster sampling: set primary sampling unit (PSU) and secondary unit weights; use Taylor-series linearization for variance.
• Stratified sampling: apply post-stratification adjustments and domain (subgroup) estimation with separate weight calibration per stratum.

3. Variance estimation & resampling

• Replication methods: implement jackknife and bootstrap replicates for robust standard errors when analytic formulas are unreliable.
• Finite population correction (FPC): apply FPC when sample fraction >5% to reduce variance bias.
