Principal Component Analysis of Binary Data. Applications to Roll-Call-Analysis

  • Author(s): de Leeuw, Jan
  • et al.
Abstract

We compute the maximum likelihood estimates of a principal component analysis on the logit or probit scalem using a majorization algorithm that computes a sequence of singular value decompositions. The technique is applied to 2001 house and senate roll call data and compared with other techniques for roll call analysis.
