UK OC OK? Interpreting Optimal Classification Scores for the U.K. House of Commons

چکیده
Poole’s (2000, Non-parametric unfolding of binary choice data. Political Analysis 8:211–37) nonparametric Optimal Classification procedure for binary data produces misleading rank orderings when applied to the modern House of Commons. With simulations and qualitative evidence, we show that the problem arises from the government-versus-opposition nature of British (Westminster) parliamentary politics and the strategic voting that is entailed therein. We suggest that political scientists think seriously about strategic voting in legislatures when interpreting results from such techniques.

The problem arises from the government-versus-opposition nature of British parliamentary politics and the strategic votin...
متن کاملThe effect of estimation methods on multifractal modeling for mineralized zone delineation in the Dardevey iron ore deposit, NE Iran
The purpose of this study is to identify the effect of Ordinary Kriging (OK) and Inverse Distance Weighted (IDW) estimation methods for the delineation of mineralized zones based on subsurface data using concentration–volume (C–V) multifractal modeling in the Dardevey iron ore deposit, NE Iran. Variograms and anisotropic ellipsoid were generated for the Fe distribution by the above estimation m...
متن کاملThe Coincident Cycles of House Prices and Consumption in the U.K.: Do House Prices Drive Consumption Growth?∗
Three mechanisms have been suggested to explain the strong correlation between house prices and consumption in the UK: wealth effects and collateral effects involve house prices driving consumption changes, but common causes may drive both house price and consumption growth simultaneously. Our contribution lies in our systematic use of a realistic structural lifecycle model of consumption and h...
متن کاملResources classification using fractal modelling in Eastern Kahang Cu-Mo porphyry deposit, Central Iran
Resources/reserves classification is crucial for block model creation utilised in mine planning and feasibility study. Selection of estimation methods is an essential part of mineral exploration and mining activities. In other word, resources classification is an issue for mining companies, investors, financial institutions and authorities, but it remains subject to some confusion. The aim of t...
