In RealVAMS: Multivariate VAM Fitting

Multivariate VAM Fitting

Description

Fits a multivariate value-added model (VAM), see Broatch, Green, and Karl (2018)
<doi:10.32614/RJ-2018-033>, and Broatch and Lohr (2012)
<doi:10.3102/1076998610396900>, with normally distributed test scores and a binary outcome indicator. A pseudo-likelihood approach, Wolfinger and O'Connell (1993)
<doi:10.1080/00949659308811554>, is used for the estimation of this joint generalized linear mixed model. The inner loop of the pseudo-likelihood routine (estimation of a linear mixed model) occurs in the framework of the EM algorithm presented by
Karl, Yang, and Lohr (2013) <DOI:10.1016/j.csda.2012.10.004>. This material is based upon work supported by the National Science Foundation under grants DRL-1336027 and DRL-1336265.
