StatVillage homework
Santrauka
During the course of sampling methods I was given a homework about hypothetical village in Canada called StatVillage. Here we try to estimate various parameters of the population variable using different sampling and estimation techniques (ex.stratified random sampling, poststratification, single-stage cluster sampling, ratio estimator). The main task is to get estimates with a low variance. In addition, missing values of numerical variables are filled in using regression trees.
