Thomas Lumley - Analysing Multistage Survey Data Using R

[@tagamag]

How does this package work when the survey data is available with sample weights at the lowest unit level? For example, if an individual survey is conducted in multiple strata/ clusters. The survey data is released by the surveyors with individual level weights, do we still have to consider the strata?

We still have to include the strata information inside the svydesign() function, we need this information to estimate the statistical information like variance.
