CSB experts develop R package “vardpoor” for variance estimation


Central Statistical Bureau (CSB) Mathematical Support Division experts Juris Breidaks and Mārtiņš Liberts have developed R package “vardpoor”. It allows estimating the precision of statistics derived from sample survey data. The main advantages of the package are its suitability for almost all types of sampling designs, easy integration into statistics production process, as well as the speed of calculations.

The package “vardpoor” has been presented in international conference for official statistics “New Challenges for Statistical Software – The Use of R in Official Statistics” held in April 2015 in Bucharest. Information on the package “vardpoor” has been published also in January issue of newsletter "The Survey Statistician" released by the International Association of Survey Statisticians (IASS) (available on IASS website http://isi-iass.org/home/wp-content/uploads/survey-statistician-january-2016.pdf).

The IASS unites survey statisticians from all over the world. It aims at promoting the study and development of the theory and practice of sample surveys and censuses, as well as at increasing interest in surveys and censuses among statisticians, governments and the public in various countries of the world.

For the first time R package “vardpoor” was published in 2014, and it is available on website https://cran.r-project.org/web/packages/vardpoor/. R is a software environment widely used for statistical computing and graphics (https://www.r-project.org). It allows user to create new functions and procedures, develop packages, thus improving R functionality.
