Anchors is a complete library of statistical functions for analyzing survey data with anchoring vignettes. The software runs on both MS-windows and linux, and can be used either with a graphical user interface (GUI) which assumes no coding by the user, as well as an extensible R library.
Anchors includes everything in King, Murray, Salomon, and Tandon (2003), as well as material from a number of areas of current research.
This software library contains functions to analyze anchoring vignettes, and runs under Stata. GLLAMM is a set of programs for estimating, predicting, and simulating Generalized Linear Latent And Mixed Models. For details, see how to run chopit within GLLAMM.
