ppsmat

The sum of squared sampling probabilities for the population, divided by the sample size, as a single number or as a vector for stratified sampling

psum

Stratum labels, of the same length as <code>psum</code>, if <code>psum</code> is a vector

strata

Matrix of pairwise sampling probabilities for the sampled individuals

jointprob

Tolerance for deciding that the covariance of sampling indicators is zero

tolerance

The Horvitz-Thompson estimator and the Hartley-Rao approximation require information in addition to the sampling probabilities for sampled individuals. These functions allow this information to be supplied.

survey

Summary statistics, two-sample tests, rank tests, generalised linear models, cumulative link models, Cox models, loglinear models, and general maximum pseudolikelihood estimation for multistage stratified, cluster-sampled, unequally weighted survey samples. Variances by Taylor series linearisation or replicate weights. Post-stratification, calibration, and raking. Two-phase subsampling designs. Graphics. PPS sampling without replacement. Principal components, factor analysis.
