Plan one estimate and check its expected precision.

Getting started with svyplan: Calculate a survey sample size, check its expected precision, and compare planning assumptions.

Choose precision targets and combine indicator or domain requirements.

Precision targets for proportions, means, and ratios: Choose an estimand, express its precision target, and interpret the planned interval.
Planning for multiple indicators and domains: Combine indicator requirements, distinguish separate from natural domains, and translate analysis units into a fieldwork sample.

Allocate samples across strata, clusters, and phases.

Stratification and sample allocation: Construct candidate strata, allocate a sample under practical constraints, and check the fieldwork allocation.
Joint allocation across indicators and domains: Build frame, measure, and target tables for one allocation that must satisfy several precision requirements.
Multistage survey planning: Estimate variance components, choose cluster counts and takes, and assess design effects and degrees of freedom.
Planning two-phase surveys and nonresponse follow-up: Allocate screening and measurement phases, account for stage-specific response, and compare with a single-phase design.

Plan overlap, attrition, fieldwork schedules, and comparisons.

Planning repeated surveys and panels: Relate precision for levels, changes, and pooled estimates to overlap, panel retention, rotation, and fieldwork schedules.
Power for comparisons and changes: Solve for per-group sample size, power, or a minimum detectable effect under independent, overlapping, and difference-in-differences designs.
