fonte primária · Read on 2026-10-15 from the copy on the rdpackages site (rdpackages.github.io/references), text layer and rendered image of page 393: the output of 'rdrobust vote margin, h(16.79369) b(27.43745)' (Kernel = Triangular, VCE method = NN, Number of obs 1297, Eff. Number of obs 343 left and 310 right, p = 1). The same row, 7.4253 (1.4954), is printed in Calonico, Cattaneo and Titiunik (2014), Stata Journal 14(4), page 939 (default bandwidth 16.794 in that version), and in their 2015 R Journal article. The research note's figures from memory (7.414, 1.459 at h = 17.754) are not what these articles print; the same 2017 article prints the new default as 7.416 (1.4604) at h = 17.708. Data check made before any estimate: 1,297 rows have both vote and margin, 595 below and 702 above zero, none exactly at zero; 343 and 310 lie within 16.79369 of zero, none exactly at the bandwidth edge, as printed.

Desvio conhecido
convenção de erro-padrão
Recorded before this track's software-reference run and before any dry run, from the printed output: rdrobust's conventional standard error uses its nearest-neighbour variance estimator ('VCE method = NN'), while infer.rdd computes HC1 and the reference follows the tool's declared HC1. The point estimate depends only on the kernel, the polynomial and the bandwidth, all fixed here; the printed cell is recorded and non-required on T1.

  1. 0Início

    Is there an incumbency advantage in U.S. Senate elections? Comparing seats the Democratic party barely won with seats it barely lost, estimate the effect of winning a Senate election on the Democratic party's share of the votes in the next election for the same seat.

    senate (agent)

    U.S. Senate elections, 1914-2010, the extract of the data of Cattaneo, Frandsen and Titiunik (2015) that ships with the rdrobust package as its illustration: one row per state and Senate election (1,390 rows). Columns: state, state code; year, year of the election; margin, the Democratic party's margin of victory in that election, in percentage points (negative when the Democratic candidate lost); vote, the Democratic party's vote share, in percent, in the next election for the same Senate seat (missing for some rows); class, the seat's Senate class (1, 2 or 3); termshouse and termssenate, terms the Democratic candidate had served in the House and in the Senate; population, the state's population.
