美国国会的DW-NOMINATE分数被广泛用于衡量立法者在一段时间内的意识形态位置。这些分数已被用于政治学和密切相关领域的大量研究。本文将刘易斯和Poole（2004）关于参数自助法的工作推广到DW-NOMINATE，得到了立法者理想点的标准误差。这些标准误差在DW-NOMINATE坐标范围的1%-4%范围内。
DW-NOMINATE scores for the U.S. Congress are widely used measures of legislators' ideological locations over time. These scores have been used in a large number of studies in political science and closely related fields. In this paper, we extend the work of Lewis and Poole (2004) on the parametric bootstrap to DW-NOMINATE and obtain standard errors for the legislator ideal points. These standard errors are in the range of 1%-4% of the range of DW-NOMINATE coordinates.
