anominate (version 0.6)

quad_anom: alpha-NOMINATE Estimate, Simulated Roll Call Matrix using Quadratic Utility

Description

alpha-NOMINATE estimates from simulated roll call matrix using quadratic utility. Estimates in one dimension.

Usage

data(quad_anom)

Value

An object of class anominate, a list with the following elements:

alpha

An object of class mcmc with the sampled values of the alpha parameter

beta

An object of class mcmc with the sampled values of the beta parameter

legislators

A object of class mcmc with the sampled values of the legislator ideal points, with each dimension stored in a separate list (e.g., the first dimension coordinates are stored in legislators[[1]], the second dimension coordinates in legislators[[2]], etc.)

yea.locations

A object of class mcmc with the sampled values of the Yea locations (midpoint - spread in W-NOMINATE) for each vote, with each dimension stored in a separate list (e.g., the first dimension coordinates are stored in yea.locations[[1]], the second dimension coordinates in yea.locations[[2]], etc.)

nay.locations

A object of class mcmc with the sampled values of the Nay locations (midpoint + spread in W-NOMINATE) for each vote, with each dimension stored in a separate list (e.g., the first dimension coordinates are stored in nay.locations[[1]], the second dimension coordinates in nay.locations[[2]], etc.)

wnom.result

An object of class nomObject with the W-NOMINATE results
