An Examination of Legislative Roll-Call Voting in the Czech Republic Using Spatial Models

Using roll-call and parliamentary survey data from the sixth legislature in the Czech Republic (2006–2008), this research demonstrates that spatial models of roll-call data are not readily explainable in terms of party cohesion and discipline. The difficulty of making a substantive interpretation of dimensions extracted suggests the use of spatial models of roll-call voting where party discipline is strong requires more theoretical and methodological work.
