sondage 0.1.0

Initial CRAN release.

Sampling methods

• srs() - Simple random sampling with or without replacement
• systematic() - Systematic sampling with random start
• bernoulli() - Bernoulli sampling (random sample size)
• up_brewer() - Brewer’s method for unequal probability sampling
• up_maxent() - Maximum entropy / Conditional Poisson sampling
• up_systematic() - Systematic sampling with unequal probabilities
• up_poisson() - Poisson sampling (random sample size)
• up_multinomial() - Unequal probability sampling with replacement

Utilities

• inclusion_prob() - Compute inclusion probabilities from measure of size

Features

• All functions return indices for direct use with df[idx, ]
• Batch sampling via up_maxent(pik, nrep = 1000) for simulations
• C implementations for performance-critical algorithms
